        Rename PatchBuffer to LinkBuffer.  Previously our terminology has been a little
        mixed up, but we have decided to fix on refering to the process that takes place
        at the end of code generation as 'linking', and on any modifications that take
        place later (and once the code has potentially already been executed) as 'patching'.

        However, the term 'PatchBuffer' is already in use, and needs to be repurposed.

        To try to minimize confusion, we're going to switch the terminology over in stages,
        so for now we'll refer to later modifications as 'repatching'.  This means that the
        new 'PatchBuffer' has been introduced with the name 'RepatchBuffer' instead.

        This patch renames the old 'PatchBuffer' to 'LinkBuffer'.  We'll leave ToT in this
        state for a week or so to try to avoid to much overlap of the meaning of the term
        'PatchBuffer', then will come back and rename 'RepatchBuffer'.

        Having moved most of their functionality into the RepatchBuffer class,
        we can simplify the CodeLocation* classes.

        The CodeLocation* classes are currently a tangle of templatey and friendly
        badness, burried in the middle of AbstractMacroAssembler.  Having moved
        the ability to repatch out into RepatchBufer they are now do-nothing wrappers
        on CodePtr (MacroAssemblerCodePtr), that only exist to provide type-safety.

        Simplify the code, and move them off into their own header.

        Having introduced the RepatchBuffer, ProcessorReturnAddress is now a do-nothing
        wrapper around ReturnAddressPtr.  Remove it.  In tugging on this piece of string
        it made sense to roll out the use of ReturnAddressPtr a little further into
        JITStubs (which had always been the intention).

        Move repatching methods into a set of methods on a class.  This will allow us to
        coallesce memory reprotection calls.  Really, we want this class to be called
        PatchBuffer, we want the class PatchBuffer to be called LinkBuffer, we want both
        to be memblers of MacroAssembler rather then AbstractMacroAssembler, we don't
        want the CodeLocationFoo types anymore (they are now only really there to provide
        type safety, and that is completely undermined by the way we use offsets).  Then
        the link & patch buffers should delegate the actual patching calls to the
        architecture-specific layer of the MacroAssembler.  Landing all these changes as a
        sequence of patches.

        We are currently generating two copies of the slow path for op_call for no reason.  Stop that.

        Originally op_call used two slow paths since the first set up the pointer to the CallLinkInfo
        for use when linking.  However this is now looked up using the return address (as we do for
        property accesses) so the two paths are now identical.

        No performance impact, reduces memory footprint.

        Encapsulate many uses of void* in the assembler & jit with types that provide
        more semantic information.  The new types are:
        
            * MacroAssemblerCodePtr - this wraps a pointer into JIT generated code.
            * FunctionPtr - this wraps a pointer to a C/C++ function in JSC.
            * ReturnAddressPtr - this wraps a return address resulting from a 'call' instruction.

        Wrapping these types allows for stronger type-checking than is possible with everything
        represented a void*.  For example, it is now enforced by the type system that near
        calls can only be linked to JIT code and not to C functions in JSC (this was previously
        required, but could not be enforced on the interface).

        Change JITStub functions from being static members on the JITStub class to be
        global extern "C" functions, and switch their the function signature declaration
        in the definition of the functions to be C-macro generated.  This makes it easier
        to work with the stub functions from assembler code (since the names no longer
        require mangling), and by delaring the functions with a macro we can look at
        also auto-generating asm thunks to wrap the JITStub functions to perform the
        work currently in 'restoreArgumentReference' (as a memory saving).

        Making this change also forces us to be a bit more realistic about what is private
        on the Register and CallFrame objects.  Presently most everything on these classes
        is private, and the classes have plenty of friends.  We could befriend all the
        global functions to perpetuate the delusion of encapsulation, but using friends is
        a bit of a sledgehammer solution here - since friends can poke around with all of
        the class's privates, and since all the major classes taht operate on Regsiters are
        currently friends, right there is currently in practice very little protection at
        all.  Better to start removing friend delclarations, and exposing just the parts
        that need to be exposed.

        Allow the JIT to operate without relying on use of RWX memory, on platforms where this is supported.

        This patch adds a switch to Platform.h (ENABLE_ASSEMBLER_WX_EXCLUSIVE) which enables this mode of operation.
        When this flag is set, all executable memory will be allocated RX, and switched to RW only whilst being
        modified.  Upon completion of code generation the protection is switched back to RX to allow execution.

        Further optimization will be required before it is desirable to enable this mode of operation by default;
        enabling this presently incurs a 5%-10% regression.

        When reseting RegexPattern class, should fully reset the class, not just bits of it.
        In particular, we delete the cached character classes (for wordchars, etc), but do
        not reset the set of pointers to the cached classes.  In the case of a repeated parse
        due to an illegal back-reference we will continue to use the deleted character class.

        Allow the buffer underlying UString to be shared.

        In order to not grow the underlying size of any structure,
        there is a union in the Rep string which holds
         + m_sharedBuffer -- a pointer to the shared ref counted buffer
           if the class is BaseString and the buffer is being shared OR
         + m_baseString -- the BaseString if the class is only UString::Rep
           but not a UString::BaseString

        Ideally, m_sharedBuffer would be a RefPtr, but it cannot be because
        it is in a union.

        op_method_check

        Optimize method calls, by caching specific function values within the Structure.
        The new opcode is used almost like an x86 opcode prefix byte to optimize op_get_by_id,
        where the property access is being used to read a function to be passed to op-call (i.e.
        'foo.bar();').  This patch modifies the Structure class such that when a property is
        put to an object for the first time we will check if the value is a function.  If it is,
        we will cache the function value on the Structure.  A Structure in such a state guarantees
        that not only does a property with the given identifier exist on the object, but also that
        its value is unchanged.  Upon any further attempt to put a property with the same identifier
        (but a different value) to the object, it will transition back to a normal Structure (where
        it will guarantee the presence but not the value of the property).

        op_method_check makes use of the new information made available by the Structure, by
        augmenting the functionality of op_get_by_id.  Upon generating a FunctionCallDotNode a
        check will be emitted prior to the property access reading the function value, and the JIT
        will generate an extra (initially unlinked but patchable) set of checks prior to the regular
        JIT code for get_by_id.  The new code will do inline structure and prototype structure check
        (unlike a regular get_by_id, which can only handle 'self' accesses inline), and then performs
        an immediate load of the function value, rather than using memory accesses to load the value
        from the obejct's property storage array.  If the method check fails it will revert, or if
        the access is polymorphic, the op_get_by_id will continue to operate - and optimize itself -
        just as any other regular op_get_by_id would.

        ~2.5% on v8-tests, due to a ~9% progression on richards.

        Refactor JIT code-handle objects.  The representation of generated code is currently
        a bit of a mess.  We have a class JITCode which wraps the pointer to a block of
        generated code, but this object does not reference the executable pool meaning that
        external events (the pool being derefed) could make the pointer become invalid.
        To overcome this both the JIT and Yarr implement further (and similar) objects to
        wrap the code pointer with a RefPtr to the pool.  To add to the mire, as well as the
        CodeBlock containing a handle onto the code the FunctionBodyNode also contains a
        copy of the code pointer which is used almost (but not entirely) uniquely to access
        the JIT code for a function.

        Rationalization of all this:

            * Add a new type 'MacroAssembler::CodeRef' as a handle for a block of JIT generated code.
            * Change the JIT & Yarr to internally handle code using CodeRefs.
            * Move the CodeRef (formerly anow defunct JITCodeRef) from CodeBlock to its owner node.
            * Remove the (now) redundant code pointer from FunctionBodyNode.

        While tidying this up I've made the PatchBuffer return code in new allocations using a CodeRef,
        and have enforced an interface that the PatchBuffer will always be used, and 'finalizeCode()' or
        'finalizeCodeAddendum()' will always be called exactly once on the PatchBuffer to complete code generation.

        This gives us a potentially useful hook ('PatchBuffer::performFinalization()') at the end of generation,
        which may have a number of uses.  It may be helpful should we wish to switch our generation
        model to allow RW/RX exclusive memory, and it may be useful on non-cache-coherent platforms to
        give us an oportunity to cache flush as necessary.

        No performance impact.

        The debugger currently retrieves the arguments object from an activation rather than pulling

        the arguments object.  In the long-term it should stop doing that (<rdar://problem/6911886>),

        Step 3: Add some actual arena allocation. About 1% SunSpider speedup.

        * JavaScriptCore.exp: Updated.

        * bytecompiler/BytecodeGenerator.cpp:
        (JSC::BytecodeGenerator::BytecodeGenerator): Updated since VarStack
        contains const Identifier* now.
        (JSC::BytecodeGenerator::emitPushNewScope): Updated to take a const
        Identifier&.
        * bytecompiler/BytecodeGenerator.h: Ditto

        * bytecompiler/SegmentedVector.h: Added isEmpty.

        * debugger/Debugger.cpp:
        (JSC::Debugger::recompileAllJSFunctions): Moved this function here from
        WebCore so WebCore doesn't need the details of FunctionBodyNode.
        * debugger/Debugger.h: Ditto.

        * interpreter/Interpreter.cpp:
        (JSC::Interpreter::execute): Updated since VarStack contains const
        Identifier* now.

        * jit/JITStubs.cpp:
        (JSC::JITStubs::cti_vm_lazyLinkCall): Call isHostFunction on the body
        rather than on the function object, since we can't easily have inlined
        access to the FunctionBodyNode in JSFunction.h since WebCore needs
        access to that header.
        (JSC::JITStubs::cti_op_construct_JSConstruct): Ditto.
        * profiler/Profiler.cpp:
        (JSC::Profiler::createCallIdentifier): Ditto.

        * parser/Grammar.y: Use JSGlobalData* to pass the global data pointer
        around whenever possible instead of using void*. Changed
        SET_EXCEPTION_LOCATION from a macro to an inline function. Marked
        the structure-creating functions inline. Changed the VarStack to use
        identifier pointers instead of actual identifiers. This takes
        advantage of the fact that all identifier pointers come from the
        arena and avoids reference count churn. Changed Identifier* to
        const Identifier* to make sure we don't modify any by accident.
        Used identifiers for regular expression strings too, using the new
        scanRegExp that has out parameters instead of the old one that relied
        on side effects in the Lexer. Move the creation of numeric identifiers
        out of this file and into the PropertyNode constructor.

        * parser/Lexer.cpp:
        (JSC::Lexer::setCode): Pass in ParserArena, used for identifiers.
        (JSC::Lexer::makeIdentifier): Changed return type to const Identifier*
        and changed to call ParserArena.
        (JSC::Lexer::scanRegExp): Added out arguments that are const Identifier*
        as well as a prefix character argument so we can handle the /= case
        without a string append.
        (JSC::Lexer::skipRegExp): Added. Skips a regular expression without
        allocating Identifier objects.
        (JSC::Lexer::clear): Removed the code to manage m_identifiers, m_pattern,
        and m_flags, and added code to set m_arena to 0.
        * parser/Lexer.h: Updated for changes above.

        * parser/NodeConstructors.h:
        (JSC::ParserArenaFreeable::operator new): Added. Calls allocateFreeable
        on the arena.
        (JSC::ParserArenaDeletable::operator new): Changed to call the
        allocateDeletable function on the arena instead of deleteWithArena.
        (JSC::RegExpNode::RegExpNode): Changed arguments to Identifier instead
        of UString since these come from the parser which makes identifiers.
        (JSC::PropertyNode::PropertyNode): Added new constructor that makes
        numeric identifiers. Some day we might want to optimize this for
        integers so it doesn't create a string for each one.
        (JSC::ContinueNode::ContinueNode): Initialize m_ident to nullIdentifier
        since it's now a const Identifier& so it can't be left uninitialized.
        (JSC::BreakNode::BreakNode): Ditto.
        (JSC::CaseClauseNode::CaseClauseNode): Updated to use SourceElements*
        to keep track of the statements rather than a separate statement vector.
        (JSC::BlockNode::BlockNode): Ditto.
        (JSC::ForInNode::ForInNode): Initialize m_ident to nullIdentifier.

        * parser/Nodes.cpp: Moved the comment explaining emitBytecode in here.
        It seemed strangely out of place in the header.
        (JSC::ThrowableExpressionData::emitThrowError): Added an overload for
        UString as well as Identifier.
        (JSC::SourceElements::singleStatement): Added.
        (JSC::SourceElements::lastStatement): Added.
        (JSC::RegExpNode::emitBytecode): Updated since the pattern and flags
        are now Identifier instead of UString. Also changed the throwError code
        to use the substitution mechanism instead of doing a string append.
        (JSC::SourceElements::emitBytecode): Added. Replaces the old
        statementListEmitCode function, since we now keep the SourceElements
        objects around.
        (JSC::BlockNode::lastStatement): Added.
        (JSC::BlockNode::emitBytecode): Changed to use emitBytecode instead of
        statementListEmitCode.
        (JSC::CaseClauseNode::emitBytecode): Added.
        (JSC::CaseBlockNode::emitBytecodeForBlock): Changed to use emitBytecode
        instead of statementListEmitCode.
        (JSC::ScopeNodeData::ScopeNodeData): Changed to store the
        SourceElements* instead of using releaseContentsIntoVector.
        (JSC::ScopeNode::emitStatementsBytecode): Added.
        (JSC::ScopeNode::singleStatement): Added.
        (JSC::ProgramNode::emitBytecode): Call emitStatementsBytecode instead
        of statementListEmitCode.
        (JSC::EvalNode::emitBytecode): Ditto.
        (JSC::EvalNode::generateBytecode): Removed code to clear the children
        vector. This optimization is no longer possible since everything is in
        a single arena.
        (JSC::FunctionBodyNode::emitBytecode): Call emitStatementsBytecode
        insetad of statementListEmitCode and check for the return node using
        the new functions.

        * parser/Nodes.h: Changed VarStack to store const Identifier* instead
        of Identifier and rely on the arena to control lifetime. Added a new
        ParserArenaFreeable class. Made ParserArenaDeletable inherit from
        FastAllocBase instead of having its own operator new. Base the Node
        class on ParserArenaFreeable. Changed the various Node classes
        to use const Identifier& instead of Identifier to avoid the need to
        call their destructors and allow them to function as "freeable" in the
        arena. Removed extraneous JSC_FAST_CALL on definitions of inline functions.
        Changed ElementNode, PropertyNode, ArgumentsNode, ParameterNode,
        CaseClauseNode, ClauseListNode, and CaseBlockNode to use ParserArenaFreeable
        as a base class since they do not descend from Node. Eliminated the
        StatementVector type and instead have various classes use SourceElements*
        instead of StatementVector. This prevents those classes from having th
        use ParserArenaDeletable to make sure the vector destructor is called.

        * parser/Parser.cpp:
        (JSC::Parser::parse): Pass the arena to the lexer.

        * parser/Parser.h: Added an include of ParserArena.h, which is no longer
        included by Nodes.h.

        * parser/ParserArena.cpp:
        (JSC::ParserArena::ParserArena): Added. Initializes the new members,
        m_freeableMemory, m_freeablePoolEnd, and m_identifiers.
        (JSC::ParserArena::freeablePool): Added. Computes the pool pointer,
        since we store only the current pointer and the end of pool pointer.
        (JSC::ParserArena::deallocateObjects): Added. Contains the common
        memory-deallocation logic used by both the destructor and the
        reset function.
        (JSC::ParserArena::~ParserArena): Changed to call deallocateObjects.
        (JSC::ParserArena::reset): Ditto. Also added code to zero out the
        new structures, and switched to use clear() instead of shrink(0) since
        we don't really reuse arenas.
        (JSC::ParserArena::makeNumericIdentifier): Added.
        (JSC::ParserArena::allocateFreeablePool): Added. Used when the pool
        is empty.
        (JSC::ParserArena::isEmpty): Added. No longer inline, which is fine
        since this is used only for assertions at the moment.

        * parser/ParserArena.h: Added an actual arena of "freeable" objects,
        ones that don't need destructors to be called. Also added the segmented
        vector of identifiers that used to be in the Lexer.

        * runtime/FunctionConstructor.cpp:
        (JSC::extractFunctionBody): Use singleStatement function rather than
        getting at a StatementVector.

        * runtime/FunctionPrototype.cpp:
        (JSC::functionProtoFuncToString): Call isHostFunction on the body
        rather than the function object.

        * runtime/JSFunction.cpp:
        (JSC::JSFunction::JSFunction): Moved the structure version of this in
        here from the header. It's not hot enough that it needs to be inlined.
        (JSC::JSFunction::isHostFunction): Moved this in here from the header.
        It's now a helper to be used only within the class.
        (JSC::JSFunction::setBody): Moved this in here. It's not hot enough that
        it needs to be inlined, and we want to be able to compile the header
        without the definition of FunctionBodyNode.

        * runtime/JSFunction.h: Eliminated the include of "Nodes.h". This was
        exposing too much JavaScriptCore dependency to WebCore. Because of this
        change and some changes made to WebCore, we could now export a lot fewer
        headers from JavaScriptCore, but I have not done that yet in this check-in.
        Made a couple functions non-inline. Removes some isHostFunction() assertions.

        Add SamplingCounter tool to provide a simple mechanism for counting events in JSC
        (enabled using ENABLE(SAMPLING_COUNTERS)).  To count events within a single function
        use the class 'SamplingCounter', where the counter may be incremented from multiple
        functions 'GlobalSamplingCounter' may be convenient; all other counters (stack or
        heap allocated, rather than statically declared) should use the DeletableSamplingCounter.
        Further description of these classes is provided alongside their definition in 
        SamplingTool.h.

        Counters may be incremented from c++ by calling the 'count()' method on the counter,
        or may be incremented by JIT code by using the 'emitCount()' method within the JIT.

        This patch also fixes CODEBLOCK_SAMPLING, which was missing a null pointer check.

        ThreadIdentifier is now a class, containing a PlatformThreadIdentifier and
        methods that are used across the code on thread ids: construction, comparisons,
        check for 'valid' state etc. '0' is used as invalid id, which happens to just work
        with all platform-specific thread id implementations.

        All the following files repeatedly reflect the new ThreadIdentifier for each platform.
        We remove ThreadMap and threadMapMutex from all of them, remove the functions that
        populated/searched/cleared the map and add platform-specific comparison operators
        for ThreadIdentifier.

        There are specific temporary workarounds for Safari 4 beta on OSX and Win32 since the
        public build uses WTF threading functions with old type of ThreadingIdentifier.
        The next time Safari 4 is rebuilt, it will 'automatically' pick up the new type and new
        functions so the deprecated ones can be removed.

        (WTF::waitForThreadCompletion): This is a workaround for Safari 4 beta on Mac.
        Safari 4 is linked against old definition of ThreadIdentifier so it treats it as uint32_t.
        This 'old' variant of waitForThreadCompletion takes uint32_t and has the old decorated name, so Safari can
        load it from JavaScriptCore library. The other functions (CurrentThread() etc) happen to match their previous
        decorated names and, while they return pthread_t now, it is a pointer which round-trips through a uint32_t.

        Changed all our JIT stubs so that they return a maximum of 1 JS value or
        two non-JS pointers, and do all other value returning through out
        parameters, in preparation for 64bit JS values on a 32bit system.

        Stubs that used to return two JSValues now return one JSValue and take
        and out parameter specifying where in the register array the second
        value should go.

        This is a simplified parser and lexer that we can throw at strings passed to eval

        Fix (kinda) for sampling tool breakage.  The codeblock sampling tool has become
        b0rked due to recent changes in native function calling.  The initialization of
        a ScopeNode appears to now occur before the sampling tool (or possibly the
        interpreter has been brought into existence, wihich leads to crashyness).

        This patch doesn't fix the problem.  The crash occurs when tracking a Scope, but
        we shouldn't need to track scopes when we're just sampling opcodes, not
        codeblocks.  Not retaining Scopes when just opcode sampling will reduce sampling
        overhead reducing any instrumentation skew, which is a good thing.  As a side
        benefit this patch also gets the opcode sampling going again, albeit in a bit of
        a lame way.  Will come back later with a proper fix from codeblock sampling.

        Previously, when appending to an existing string and growing the underlying buffer,
        we would actually allocate 110% of the required size in order to give us some space
        to expand into.  Now we treat strings differently based on their size:

        Small Strings (up to 4 pages):
        Expand the allocation size to 112.5% of the amount requested.  This is largely sicking
        to our previous policy, however 112.5% is cheaper to calculate.

        Medium Strings (up to 128 pages):
        For pages covering multiple pages over-allocation is less of a concern - any unused
        space will not be paged in if it is not used, so this is purely a VM overhead.  For
        these strings allocate 2x the requested size.

        Large Strings (to infinity and beyond!):
        Revert to our 112.5% policy - probably best to limit the amount of unused VM we allow
        any individual string be responsible for.

        Additionally, round small allocations up to a multiple of 16 bytes, and medium and
        large allocations up to a multiple of page size.

        ~1.5% progression on Sunspider, due to 5% improvement on tagcloud & 15% on validate.

        Change WTF::ThreadIdentifier to be an actual (but wrapped) thread id, remove ThreadMap.

        (WTF::ThreadIdentifier::isValid):
        (WTF::ThreadIdentifier::invalidate):
        (WTF::ThreadIdentifier::platformId):
        ThreadIdentifier is now a class, containing a PlatformThreadIdentifier and
        methods that are used across the code on thread ids: construction, comparisons,
        check for 'valid' state etc. '0' is used as invalid id, which happens to just work
        with all platform-specific thread id implementations.

        All the following files repeatedly reflect the new ThreadIdentifier for each platform.
        We remove ThreadMap and threadMapMutex from all of them, remove the functions that
        populated/searched/cleared the map and add platform-specific comparison operators
        for ThreadIdentifier.

        (WTF::ThreadIdentifier::operator!=):
        (WTF::initializeThreading):
        (WTF::createThreadInternal): All the platforms (except Windows) used a sequential
        counter as a thread ID and mapped it into platform ID. Windows was using native thread
        id and mapped it into thread handle. Since we can always obtain a thread handle
        by thread id, createThread now closes the handle.

        Fix crash due to incorrectly using an invalid scopechain 

        stringProtoFuncReplace was checking for an exception on a CachedCall
        by asking for the cached callframes exception.  Unfortunately this
        could crash in certain circumstances as CachedCall does not guarantee
        a valid callframe following a call.  Even more unfortunately the check
        was entirely unnecessary as there is only a single exception slot per
        global data, so it was already checked via the initial exec->hadException()
        check.

        To make bugs like this more obvious, i've added a debug only destructor
        to ScopeChainNode that 0's all of its fields.  This exposed a crash in
        the standard javascriptcore tests.

        Detect patterns corresponding to string concatenation, and change the bytecode
        generation to emit a new op_strcat instruction.  By handling the full set of
        additions within a single function we do not need allocate JSString wrappers

        prior to allocating storage, in order to prevent reallocation of the buffer.

        Frameworks can be disabled by passing CONFIG+=webkit_no_framework

        To be able to build both debug and release targets in parallel
        we have to use separate output directories for the generated

        Bug 25559: Improve native function call performance
        <https://bugs.webkit.org/show_bug.cgi?id=25559>

        In order to cache calls to native functions we now make the standard
        prototype functions use a small assembly thunk that converts the JS
        calling convention into the native calling convention.  As this is
        only beneficial in the JIT we use the NativeFunctionWrapper typedef
        to alternate between PrototypeFunction and JSFunction to keep the
        code sane.  This change from PrototypeFunction to NativeFunctionWrapper
        is the bulk of this patch.

        (JSC::Lexer::record16): Moved up higher in the file.
        (JSC::Lexer::lex): Changed type of stringType to int. Replaced m_skipLF
        and m_skipCR with m_skipLineEnd, which requires fewer branches in the
        main lexer loop. Use currentOffset instead of m_currentOffset. Removed
        unneeded m_stackToken. Use isASCIIDigit instead of isDecimalDigit.
        Split out the two cases for InIdentifierOrKeyword and InIdentifier.
        Added special case tight loops for identifiers and other simple states.
        Removed a branch from the code that sets m_atLineStart to false using goto.
        Streamlined the number-handling code so we don't check for the same types
        twice for non-numeric cases and don't add a null to m_buffer8 when it's
        not being used. Removed m_eatNextIdentifier, which wasn't working anyway,
        and m_restrKeyword, which is redundant with m_lastToken. Set the
        m_delimited flag without using a branch.
        (JSC::Lexer::scanRegExp): Tweaked style a bit.
        (JSC::Lexer::clear): Clear m_codeWithoutBOMs so we don't use memory after
        parsing. Clear out UString objects in the more conventional way.
        (JSC::Lexer::sourceCode): Made this no-longer inline since it has more
        work to do in the case where we stripped BOMs.

        * parser/Lexer.h: Renamed yylineno to m_lineNumber. Removed convertHex
        function, which is the same as toASCIIHexValue. Removed isHexDigit
        function, which is the same as isASCIIHedDigit. Replaced shift with four
        separate shift functions. Removed isWhiteSpace function that passes
        m_current, instead just passing m_current explicitly. Removed isOctalDigit,
        which is the same as isASCIIOctalDigit. Eliminated unused arguments from
        matchPunctuator. Added copyCoodeWithoutBOMs and currentOffset. Moved the
        makeIdentifier function out of the header. Added lastTokenWasRestrKeyword
        function. Added new constants for m_skipLineEnd. Removed unused yycolumn,
        m_restrKeyword, m_skipLF, m_skipCR, m_eatNextIdentifier, m_stackToken,
        m_position, m_length, m_currentOffset, m_nextOffset1, m_nextOffset2,
        m_nextOffset3. Added m_skipLineEnd, m_codeStart, m_codeEnd, and
        m_codeWithoutBOMs.

        Add mechanism to vend heap allocated JS numbers to JavaScriptCore API clients with a
        representation that is independent of the number representation in the VM.
        - Numbers leaving the interpreter are converted to a tagged JSNumberCell.
        - The numbers coming into the interpreter (asserted to be the tagged JSNumberCell) are
          converted back to the VM's internal number representation.

        Add SamplingFlags mechanism.

        This mechanism allows fine-grained JSC and JavaScript program aware
        performance measurement.  The mechanism provides a set of 32 flags,
        numbered #1..#32.  Flag #16 is initially set, and all other flags
        are cleared.  Flags may be set and cleared from within

        Enable by setting ENABLE_SAMPLING_FLAGS to 1 in wtf/Platform.h.
        Disabled by default, no performance impact.  Flags may be modified
        by calling SamplingFlags::setFlag() and SamplingFlags::clearFlag()
        from within JSC implementation, or by calling setSamplingFlag() and
        clearSamplingFlag() from JavaScript.

        The flags are sampled with a frequency of 10000Hz, and the highest
        set flag in recorded, allowing multiple events to be measured (with
        the highest flag number representing the highest priority).

        Disabled by default; no performance impact.

        Coallesce input checking and reduce futzing with the index position
        between alternatives and iterations of the main loop of a regex,
        when run in YARR.

        Consider the following regex:  /foo|bar/
        
        Prior to this patch, this will be implemented something like this pseudo-code description:
        
        loop:
            check_for_available_input(3) // this increments the index by 3, for the first alterantive.
                if (available) { test "foo" }
            decrement_index(3)
            check_for_available_input(3) // this increments the index by 3, for the second alterantive.
                if (available) { test "bar" }
            decrement_index(3)
            check_for_available_input(1) // can we loop again?
                if (available) { goto loop }

        With these changes it will look more like this:

            check_for_available_input(3) // this increments the index by 3, for the first alterantive.
            if (!available) { goto fail }
        loop:
            test "foo"
            test "bar"
            check_for_available_input(1) // can we loop again?
                if (available) { goto loop }
        fail:


        This gives about a 5% gain on v8-regex, no change on Sunspider.

        Improve function.apply performance

        Jump through a few hoops to improve performance of function.apply in the general case.

        In the case of zero or one arguments, or if there are only two arguments and the
        second is an array literal we treat function.apply as function.call.

        Otherwise we use the new opcodes op_load_varargs and op_call_varargs to do the .apply call
        without re-entering the virtual machine.

        dtoa.cpp segfaults with g++ 4.4.0

        g++ 4.4.0 seems to be more strict about aliasing rules, so it
        produces incorrect code if dtoa.cpp is compiled with
        -fstrict-aliasing (it also emits a ton of warnings, so fair enough
        I guess). The problem was that we were only casting variables to
        union types in order to do type punning, but GCC and the C
        standard require that we actually use a union to store the value.

        This patch does just that, the code is mostly copied from the dtoa

        Fixed <rdar://problem/6279213> Regular expression run-time complexity
        limit too low for long inputs (21485)
        
        I raised PCRE's "matchLimit" (limit on backtracking) by an order of
        magnitude. This fixes all the reported examples of timing out on legitimate
        regular expression matches.
        
        In my testing on a Core Duo MacBook Pro, the longest you can get stuck
        trying to match a string is still under 1s, so this seems like a safe change.
        
        I can think of a number of better solutions that are more complicated,
        but this is a good improvement for now.

        <rdar://problem/6657774>

        r41508 actually exposed a pre-existing bug where we were not invalidating the result
        register cache at jump targets.  This causes problems when condition loads occur in an
        expression -- namely through the ?: and || operators.  This patch corrects these issues
        by marking the target of all forward jumps as being a jump target, and then clears the
        result register cache when ever it starts generating code for a targeted instruction.

        I do not believe it is possible to cause this class of failure outside of a single
        expression, and expressions only provide forward branches, so this should resolve this
        entire class of bug.  That said i've included a test case that gets as close as possible
        to hitting this bug with a back branch, to hopefully prevent anyone from introducing the
        problem in future.

        <rdar://problem/6354858> FastMallocZone's enumeration code reports fragmented administration space

        The handling of MALLOC_ADMIN_REGION_RANGE_TYPE in FastMalloc's zone was incorrect.  It was attempting
        to record the memory containing and individual span as an administrative region, when all memory
        allocated via MetaDataAlloc should in fact be recorded.  This was causing memory regions allocated
        via MetaDataAlloc to appear as "VM_ALLOCATE ?" in vmmap output.  They are now correctly reported as
        "MALLOC_OTHER" regions associated with the JavaScriptCore FastMalloc zone.

        Memory is allocated via MetaDataAlloc from two locations: PageHeapAllocator, and TCMalloc_PageMap{2,3}.
        These two cases are handled differently.

        PageHeapAllocator is extended to keep a linked list of memory regions that it has allocated.  The
        first object in an allocated region contains the link to the previously allocated region. To record
        the administrative regions of a PageHeapAllocator we can simply walk the linked list and record
        each allocated region we encounter.

        TCMalloc_PageMaps allocate memory via MetaDataAlloc to store each level of the radix tree.  To record
        the administrative regions of a TCMalloc_PageMap we walk the tree and record the storage used for nodes
        at each position rather than the nodes themselves.

        A small performance improvement is achieved by coalescing adjacent memory regions inside the PageMapMemoryUsageRecorder
        so that fewer calls in to the range recorder are necessary.  We further reduce the number of calls to the
        range recorder by aggregating the in-use ranges of a given memory region into a local buffer before recording
        them with a single call.  A similar approach is also used by AdminRegionRecorder.

        By looking in grammar.y there are only a few types of statement nodes
        on which the debugger should stop. 

        Removed isBlock and isLoop virtual calls. No need to emit debug hooks in
        the "statementListEmitCode" method as long as the necessary hooks can be
        added in each "emitCode".

        Integer Immediate representation need not be canonical in x86 JIT code.
        On x86-64 we already have loosened the requirement that the int immediate

        This patch is a minor (~0.5%) improvement on sunspider & v8-tests, and

        Bug 24086: Regression (r40993): WebKit crashes after logging in to lists.zenbe
        <https://bugs.webkit.org/show_bug.cgi?id=24086>
        <rdar://problem/6625111>

        The numeric sort optimization in r40993 generated bytecode for a function
        without generating JIT code. This breaks an assumption in some parts of
        the JIT's function calling logic that the presence of a CodeBlock implies
        the existence of JIT code.

        In order to fix this, we simply generate JIT code whenever we check whether
        a function is a numeric sort function. This only incurs an additional cost
        in the case when the function is a numeric sort function, in which case it
        is not expensive to generate JIT code for it.

        The bug was that for-in enumeration used a cached prototype chain without

        This led me to refactor prototype chain caching so it was easier to work

        Remove (/reduce) use of hard-wired register names from the JIT.
        Currently there is no abstraction of registers used in the JIT,
        which has a number of negative consequences.  Hard-wiring x86
        register names makes the JIT less portable to other platforms,
        and prevents us from performing dynamic register allocation to
        attempt to maintain more temporary values in machine registers.
        (The latter will be more important on x86-64, where we have more
        registers to make use of).

        Also, remove MacroAssembler::mod32.  This was not providing a
        useful abstraction, and was not in keeping with the rest of the
        MacroAssembler interface, in having specific register requirements.

        When throwing an exception within an eval argument string, the dst parameter was
        modified in the functions below and the return value for eval was altered. Changed
        the emitNode call in JSC::ThrowNode::emitBytecode to use a temporary register
        to store its results instead of dst. The JSC::FunctionCallResolveNode::emitBytecode
        would load the function within the dst registry, also altering the result returned
        by eval. Replaced it with another temporary.

        A more sensible register allocation for x86-64.

        When WREC was ported to x86-64 it stuck with the same register allocation as x86.
        This requires registers to be reordered on entry into WREC generated code, since

        This patch tidies up the MacroAssembler, cleaning up the code and refactoring out the
        platform-specific parts.  The MacroAssembler gets split up like a beef burger, with the
        platform-agnostic data types being the lower bun (in the form of the class AbstractMacroAssembler),
        the plaform-specific code generation forming a big meaty patty of methods like 'add32',
        'branch32', etc (MacroAssemblerX86), and finally topped off with the bun-lid of the
        MacroAssembler class itself, providing covenience methods such as the stack peek & poke,
        and backwards branch methods, all of which can be described in a platform independent
        way using methods from the base class.  The AbstractMacroAssembler is templated on the
        type of the assembler class that will be used for code generation, and the three layers
        are held together with the cocktail stick of inheritance.

        The above description is a slight simplification since the MacroAssemblerX86 is actually
        formed from two layers (in effect giving us a kind on bacon double cheeseburger) - with the
        bulk of methods that are common between x86 & x86-64 implemented in MacroAssemblerX86Common,
        which forms a base class for MacroAssemblerX86 and MacroAssemblerX86_64 (which add the methods
        specific to the given platform).

        I'm landing these changes first without splitting the classes across multiple files,
        I will follow up with a second patch to split up the file MacroAssembler.h.

        global object. The fix is to make the didExecute() call use the caller's
        CallFrame, not the one made for the function call. In this case, the
        willExecute() call should also be changed to match.

        Since this occurs in the actual inspector JS, it is difficult to reduce.
        I couldn't make a layout test.

        Make the JSImmediate interface private.

        All manipulation of JS values should be through the JSValuePtr class, not by using JSImmediate
        directly.  The key missing methods on JSValuePtr are:

            * isCell() - check for values that are JSCell*s, and as such where asCell() may be used.
            * isInt32Fast() getInt32Fast() - fast check/access for integer immediates.
            * isUInt32Fast() getUInt32Fast() - ditto for unsigned integer immediates.

        The JIT is allowed full access to JSImmediate, since it needs to be able to directly
        manipulate JSValuePtrs.  The Interpreter is provided access to perform operations directly
        on JSValuePtrs through the new JSFastMath interface.

        No performance impact.

        Bug 23239: improve handling of unused arguments in JavaScriptCore

        * runtime/DatePrototype.cpp: Moved LocaleDateTimeFormat enum outside #if
        so we can use this on all platforms. Changed valueOf to share the same
        function with getTime, since the contents of the two are identical. Removed
        a FIXME since the idea isn't really specific enough or helpful enough to
        need to sit here in the source code.
        (JSC::formatLocaleDate): Changed the Mac version of this function to take
        the same arguments as the non-Mac version so the caller doesn't have to
        special-case the two platforms. Also made the formatString array be const;
        before the characters were, but the array was a modifiable global variable.
        (JSC::dateProtoFuncToLocaleString): Changed to call the new unified

        which should happen for all allocators (due to aligning pointers, int's, etc. on 4 byte boundaries).

        Encode immediates in the low word of JSValuePtrs, on x86-64.

        On 32-bit platforms a JSValuePtr may represent a 31-bit signed integer.
        On 64-bit platforms, if USE(ALTERNATE_JSIMMEDIATE) is defined, a full
        32-bit integer may be stored in an immediate.
        
        Presently USE(ALTERNATE_JSIMMEDIATE) uses the same encoding as the default
        immediate format - the value is left shifted by one, so a one bit tag can
        be added to indicate the value is an immediate.  However this means that
        values must be commonly be detagged (by right shifting by one) before
        arithmetic operations can be performed on immediates.  This patch modifies
        the formattting so the the high bits of the immediate mark values as being
        integer.

        Don't store exception information for a CodeBlock until first exception is thrown

        - Change the process for re-parsing/re-generating bytecode for exception information

        Replace accidentally removed references in BytecodeGenerator, deleting these
        will be hindering the sharing of constant numbers and strings.

        The code to add a new constant (either number or string) to their respective
        map works by attempting to add a null entry, then checking the result of the
        add for null.  The first time, this should return the null (or noValue).
        The code checks for null (to see if this is the initial add), and then allocates
        a new number / string object.  This code relies on the result returned from
        the add to the map being stored as a reference, such that the allocated object
        will be stored in the map, and will be resused if the same constant is encountered
        again.  By failing to use a reference we will be leaking GC object for each
        additional entry added to the map.  As GC objects they should be clollected,
        be we should no be allocatin them in the first place.

        Replace all uses of JSValue* with a new smart pointer type, JSValuePtr.
        
        A JavaScript value may be a heap object or boxed primitive, represented by a
        pointer, or may be an unboxed immediate value, such as an integer.  Since a
        value may dynamically need to contain either a pointer value or an immediate,
        we encode immediates as pointer values (since all valid JSCell pointers are
        allocated at alligned addesses, unaligned addresses are available to encode
        immediates).  As such all JavaScript values are represented using a JSValue*.

        This implementation is encumbered by a number of constraints.  It ties the
        JSValue representation to the size of pointer on the platform, which, for
        example, means that we currently can represent different ranges of integers
        as immediates on x86 and x86-64.  It also prevents us from overloading the
        to-boolean conversion used to test for noValue() - effectively forcing us
        to represent noValue() as 0.  This would potentially be problematic were we
        to wish to encode integer values differently (e.g. were we to use the v8
        encoding, where pointers are tagged with 1 and integers with 0, then the
        immediate integer 0 would conflict with noValue()).

        This patch replaces all usage of JSValue* with a new class, JSValuePtr,
        which encapsulates the pointer.  JSValuePtr maintains the same interface as
        JSValue*, overloading operator-> and operator bool such that previous
        operations in the code on variables of type JSValue* are still supported.

        In order to provide a ProtectPtr<> type with support for the new value
        representation (without using the internal JSValue type directly), a new
        ProtectJSValuePtr type has been added, equivalent to the previous type
        ProtectPtr<JSValue>.

        This patch is likely the first in a sequence of three changes.  With the
        value now encapsulated it will likely make sense to migrate the functionality
        from JSValue into JSValuePtr, such that the internal pointer representation
        need not be exposed.  Through migrating the functionality to the wrapper
        class the existing JSValue should be rendered redundant, and the class is
        likely to be removed (the JSValuePtr now wrapping a pointer to a JSCell).
        At this stage it will likely make sense to rename JSValuePtr to JSValue.

        <https://bugs.webkit.org/show_bug.cgi?id=23085> [jsfunfuzz] Over released ScopeChainNode
        <rdar://problem/6474110>

        So this delightful bug was caused by our unwind code using a ScopeChain to perform
        the unwind.  The ScopeChain would ref the initial top of the scope chain, then deref
        the resultant top of scope chain, which is incorrect.

        This patch removes the dependency on ScopeChain for the unwind, and i've filed
        <https://bugs.webkit.org/show_bug.cgi?id=23144> to look into the unintuitive
        ScopeChain behaviour.

        CanvasPixelArray performance is too slow 
        <https://bugs.webkit.org/show_bug.cgi?id=23123>

        The fix to this is to devirtualise get and put in a manner similar to
        JSString and JSArray.  To do this I've added a ByteArray implementation
        and JSByteArray wrapper to JSC.  We can then do vptr comparisons to
        devirtualise the calls.

        This devirtualisation improves performance by 1.5-2x in my somewhat ad
        hoc tests.

        This bug was caused by eval codeblocks being generated without accounting

        Allow 32-bit integers to be stored in JSImmediates, on x64-bit.
        Presently the top 32-bits of a 64-bit JSImmediate serve as a sign extension of a 31-bit
        int stored in the low word (shifted left by one, to make room for a tag).  In the new
        format, the top 31-bits serve as a sign extension of a 32-bit int, still shifted left by
        one.

        The new behavior is enabled using a flag in Platform.h, 'WTF_USE_ALTERNATE_JSIMMEDIATE'.
        When this is set the constants defining the range of ints allowed to be stored as
        JSImmediate values is extended.  The code in JSImmediate.h can safely operate on either
        format.  This patch updates the JIT so that it can also operate with the new format.

        ~2% progression on x86-64, with & without the JIT, on sunspider & v8 tests.

        Bug 23037: Parsing and reparsing disagree on automatic semicolon insertion
        <https://bugs.webkit.org/show_bug.cgi?id=23037>
        <rdar://problem/6467124>

        Parsing and reparsing disagree about automatic semicolon insertion, so that a
        function like

        function() { a = 1, }

        is parsed as being syntactically valid but gets a syntax error upon reparsing.
        This leads to an assertion failure in Parser::reparse(). It is not that big of
        an issue in practice, because in a Release build such a function will return
        'undefined' when called.

        In this case, we are not following the spec and it should be a syntax error.
        However, unless there is a newline separating the ',' and the '}', WebKit would
        not treat it as a syntax error in the past either. It would be a bit of work to
        make the automatic semicolon insertion match the spec exactly, so this patch
        changes it to match our past behaviour.

        The problem is that even during reparsing, the Lexer adds a semicolon at the
        end of the input, which confuses allowAutomaticSemicolon(), because it is
        expecting either a '}', the end of input, or a terminator like a newline.

        <rdar://problem/6358108> Insecure randomness in Math.random() leads to user tracking

        Switch to arc4random on PLATFORM(DARWIN), this is ~1.5x slower than random(), but the

        Fix rounding / bounds / signed comparison bug in ExecutableAllocator.

        ExecutableAllocator::alloc assumed that m_freePtr would be aligned.  This was
        not always true, since the first allocation from an additional pool would not
        be rounded up.  Subsequent allocations would be unaligned, and too much memory
        could be erroneously allocated from the pool, when the size requested was
        available, but the size rounded up to word granularity was not available in the
        pool.  This may result in the value of m_freePtr being greater than m_end.

        Under these circumstances, the unsigned check for space will always pass,
        resulting in pointers to memory outside of the arena being returned, and
        ultimately segfaulty goodness when attempting to memcpy the hot freshly jitted
        code from the AssemblerBuffer.

        Fixes for the JIT's handling of JSImmediate values on x86-64.
        On 64-bit systems, the code in JSImmediate.h relies on the upper
        bits of a JSImmediate being a sign extension of the low 32-bits.
        This was not being enforced by the JIT, since a number of inline
        operations were being performed on 32-bit values in registers, and
        when a 32-bit result is written to a register on x86-64 the value
        is zero-extended to 64-bits.
        
        This fix honors previous behavoir.  A better fix in the long run
        (when the JIT is enabled by default) may be to change JSImmediate.h
        so it no longer relies on the upper bits of the pointer,... though
        if we're going to change JSImmediate.h for 64-bit, we probably may
        as well change the format so that the full range of 32-bit ints can
        be stored, rather than just 31-bits.

        Make the JIT compile on x86-64.
        This largely involves populting the missing calls in MacroAssembler.h.
        In addition some reinterpret_casts need removing from the JIT, and the
        repatching property access code will need to be fully compiled out for
        now.  The changes in interpret.cpp are to reorder the functions so that
        the _generic forms come before all other property access methods, and
        then to place all property access methods other than the generic forms
        under control of the ENABLE_JIT_OPTIMIZE_PROPERTY_ACCESS macro.

        Bug 22869: REGRESSION (r38407): http://news.cnet.com/8301-13579_3-9953533-37.html crashes
        <https://bugs.webkit.org/show_bug.cgi?id=22869>
        <rdar://problem/6402499>

        Before r38407, Structure::m_nameInPrevious was ref'd due to it being
        stored in a PropertyMap. However, PropertyMaps are created lazily after
        r38407, so Structure::m_nameInPrevious is not necessarily ref'd while
        it is being used. Making it a RefPtr instead of a raw pointer fixes
        the problem.

        Unfortunately, the crash in the bug is rather intermittent, and it is
        impossible to add an assertion in UString::Ref::ref() to catch this bug
        because some users of UString::Rep deliberately zero out the reference
        count. Therefore, there is no layout test accompanying this bug fix.

        the code taking care of initializing the random number generator (only when
        building without ENABLE(JSC_MULTIPLE_THREADS), otherwhise initializeThreading()
        already took care of that).

        Functional change on darwin: Use random() instead of rand(), as it got a larger
        period (more randomness). HTMLFormElement already contains this implementation
        and I just moved it in randomNumber(), as  special case for PLATFORM(DARWIN).

        more sensible (1-based incrementing by 1, rather than 0-based incrementing by 4).  The CTI name also seems
        to be being deprecated from the code generally.

        <https://bugs.webkit.org/show_bug.cgi?id=22828>

        In order to remove the bytecode instruction stream after generating
        native code, all inspection of bytecode instructions at runtime must
        be removed. One particular instance of this is the special handling of
        exceptions thrown by the op_get_by_id emitted directly before an
        op_construct or an op_instanceof. This patch moves that information to
        an auxiliary data structure in CodeBlock.

        Remove dependancy on having the Instruction buffer in order to

        Instead, we put references to the necessary Structures in auxiliary
        data structures on the CodeBlock. This is not an ideal solution,
        as we still pay for having the Structures in two places and we

        Generally adds more operations and permutations of operands to the existing

        Add a new allocator for use by the JIT that provides executable pages, so

        Remove m_assembler from MacroAssembler::Jump.
        Keeping a pointer allowed for some syntactic sugar - "link()" looks nicer
        than "link(this)".  But maintaining this doubles the size of Jump, which
        is even more unfortunate for the JIT, since there are many large structures
        holding JmpSrcs.  Probably best to remove it.

        Bug 22504: Crashes during code generation occur due to refing of ignoredResult()
        <https://bugs.webkit.org/show_bug.cgi?id=22504>

        Since ignoredResult() was implemented by casting 1 to a RegisterID*, any
        attempt to ref ignoredResult() results in a crash. This will occur in
        code generation of a function body where a node emits another node with
        the dst that was passed to it, and then refs the returned RegisterID*.

        To fix this problem, make ignoredResult() a member function of
        BytecodeGenerator that simply returns a pointe to a fixed RegisterID
        member of BytecodeGenerator.

        REGRESSION (r38745): Assertion failure in jsSubstring() at ge.com

        The bug was that index would become greater than length, so our
        "end of input" checks, which all check "index == length", would fail.
        
        The solution is to check for end of input before incrementing index,
        to ensure that index is always <= length.
        
        As a side benefit, generateJumpIfEndOfInput can now use je instead of
        jg, which should be slightly faster.

        Bug 20340: SegmentedVector segment allocations can lead to unsafe use of temporary registers
        <https://bugs.webkit.org/show_bug.cgi?id=20340>

        SegmentedVector currently frees segments and reallocates them when used
        as a stack. This can lead to unsafe use of pointers into freed segments.

        In order to fix this problem, SegmentedVector will be changed to only
        grow and never shrink. Also, rename the reserveCapacity() member
        function to grow() to match the actual usage in BytecodeGenerator, where
        this function is used to allocate a group of registers at once, rather
        than merely saving space for them.

        Enable WREC on PLATFORM(X86_64).  This change predominantly requires changes to the

        support for a limited number of quadword operations in the X86Assembler.

        Polymorpic caching for get by id chain.  Similar to the polymorphic caching already implemented
        for self and proto accesses (implemented by allowing multiple trampolines to be JIT genertaed,
        and linked together) - the get by id chain caching is implemented as a genericization of the
        proto list caching, allowing cached access lists to contain a mix of proto and proto chain
        accesses (since in JS style inheritance hierarchies you may commonly see a mix of properties
        being overridden on the direct prototype, or higher up its prototype chain).

        In order to allow this patch to compile there is a fix to appease gcc 4.2 compiler issues
        (removing the jumps between fall-through cases in privateExecute).
        
        This patch also removes redundant immediate checking from the reptach code, and fixes a related
        memory leak (failure to deallocate trampolines).

        Add support for (really) polymorphic caching of prototype accesses.
        
        If a cached prototype access misses, cti_op_get_by_id_proto_list is called.
        When this occurs the Structure pointers from the instruction stream are copied
        off into a new ProtoStubInfo object.  A second prototype access trampoline is
        generated, and chained onto the first.  Subsequent missed call to
        cti_op_get_by_id_proto_list_append, which append futher new trampolines, up to
        PROTOTYPE_LIST_CACHE_SIZE (currently 4).  If any of the misses result in an
        access other than to a direct prototype property, list formation is halted (or
        for the initial miss, does not take place at all).

        Separate fail case functions are provided for each access since this contributes
        to the performance progression (enables better processor branch prediction).

        Overall this is a near 5% progression on v8, with around 10% wins on richards

        <rdar://problem/6390179>
        Lazily reparse FunctionBodyNodes on first execution.

        - Saves 57MB on Membuster head.

        * bytecompiler/BytecodeGenerator.cpp:
        (JSC::BytecodeGenerator::generate): Remove vector shrinking since this is now
        handled by destroying the ScopeNodeData after generation.

        * parser/Grammar.y: Add alternate NoNode version of the grammar
        that does not create nodes.  This is used to lazily create FunctionBodyNodes
        on first execution.

        * parser/Lexer.cpp:
        (JSC::Lexer::setCode): Fix bug where on reparse, the Lexer was confused about
        what position and length meant. Position is the current position in the original
        data buffer (important for getting correct line/column information) and length
        the end offset in the original buffer.
        * parser/Lexer.h:
        (JSC::Lexer::sourceCode): Positions are relative to the beginning of the buffer.

        * parser/Nodes.cpp:
        (JSC::ScopeNodeData::ScopeNodeData): Move initialization of ScopeNode data here.
        (JSC::ScopeNode::ScopeNode): Add constructor that only sets the JSGlobalData
        for FunctionBodyNode stubs.
        (JSC::ScopeNode::~ScopeNode): Release m_children now that we don't inherit from
        BlockNode.

        to construct it. Then after generation, destroy the data.
        (JSC::ProgramNode::generateBytecode): After generation, destroy the AST data.
        * parser/Nodes.h:

        * parser/Parser.cpp:
        (JSC::Parser::reparse): Reparse the SourceCode in the FunctionBodyNode and set
        set up the ScopeNodeData for it. 
        * parser/Parser.h:

        * parser/SourceCode.h:
        (JSC::SourceCode::endOffset): Added for use in the lexer.

        * runtime/FunctionConstructor.cpp:
        (JSC::getFunctionBody): Assuming a ProgramNode with one FunctionExpression in it,
        get the FunctionBodyNode.  Any issues signifies a parse failure in constructFunction. 
        (JSC::constructFunction): Make parsing functions in the form new Function(""), easier
        by concatenating the strings together (with some glue) and parsing the function expression
        as a ProgramNode from which we can receive the FunctionBodyNode. This has the added benefit
        of not having special parsing code for the arguments and lazily constructing the 
        FunctionBodyNode's AST on first execution.

        * runtime/Identifier.h:
        (JSC::operator!=): Added.

        Minor RegExp cleanup.
        
        SunSpider says no change.

        * runtime/RegExpObject.cpp:
        (JSC::RegExpObject::match): Renamed "regExpObj" to "regExpConstructor".

        * wrec/WREC.cpp:
        (JSC::WREC::compileRegExp): Instead of checking for a NULL output vector,
        ASSERT that the output vector is not NULL. (The rest of WREC is not
        safe to use with a NULL output vector, and we probably don't want to
        spend the time and/or performance to make it safe.)

        A little more renaming and refactoring.
        
        VM_CHECK_EXCEPTION() => CHECK_FOR_EXCEPTION().
        NEXT_INSTRUCTION => NEXT_INSTRUCTION().

        Removed the "Error_" and "TempError_" prefixes from WREC error types.

        Refactored the WREC parser so it doesn't need a "setError" function,
        and changed "isEndOfPattern" and its use -- they read kind of backwards
        before.
        
        Changed our "TODO:" error messages at least to say something, since you
        can't say "TODO:" in shipping software.

        Reviewed by Sam Weinig.

        A few more renames:

        BytecodeInterpreter => Interpreter
        WREC => JSC::WREC, removing JSC:: prefix in a lot of places
        X86Assembler::copy => X86Assembler::executableCopy
        AssemblerBuffer::copy => AssemblerBuffer::executableCopy
        WRECFunction => WREC::RegExpFunction
        OBJECT_OFFSET => FIELD_OFFSET
        
        Also:

        Nixed use of OBJECT_OFFSET outside of CTI.cpp by making CTI a friend in more places.
        Nixed X86:: and X86Assembler:: prefixes in a lot of places using typedefs

        Bug 22259: Make all opcodes use eax as their final result register

        Change one case of op_add (and the corresponding slow case) to use eax
        rather than edx. Also, change the order in which the two results of
        resolve_func and resolve_base are emitted so that the retrieved value is
        put last into eax.

        This gives no performance change on SunSpider or the V8 benchmark suite

        Remove use of static C++ objects that are destroyed at exit time (destructors)

        Create DEFINE_STATIC_LOCAL macro. Change static local objects to leak to avoid 
        exit-time destructor. Update code that was changed to fix this issue that ran 
        into a gcc bug (<rdar://problem/6354696> Codegen issue with C++ static reference 
        in gcc build 5465). Also typdefs for template types needed to be added in some 
        cases so the type could make it through the macro successfully.

        Basically code of the form:
        static T m;
        becomes:
        DEFINE_STATIC_LOCAL(T, m, ());

        Also any code of the form:
        static T& m = *new T;

        Fix for https://bugs.webkit.org/show_bug.cgi?id=22269
        Reduce PropertyMap usage

        From observation of StructureID statistics, it became clear that many
        StructureID's were not being used as StructureIDs themselves, but rather
        only being necessary as links in the transition chain.  Acknowledging this
        and that PropertyMaps stored in StructureIDs can be treated as caches, that
        is that they can be reconstructed on demand, it became clear that we could
        reduce the memory consumption of StructureIDs by only keeping PropertyMaps
        for the StructureIDs that need them the most.

        The specific strategy used to reduce the number of StructureIDs with
        PropertyMaps is to take the previous StructureIDs PropertyMap when initially
        transitioning (addPropertyTransition) from it and clearing out the pointer 
        in the process.  The next time we need to do the same transition, for instance
        repeated calls to the same constructor, we use the new addPropertyTransitionToExistingStructure
        first, which allows us not to need the PropertyMap to determine if the property
        exists already, since a transition to that property would require it not already
        be present in the StructureID.  Should there be no transition, the PropertyMap
        can be constructed on demand (via materializePropertyMap) to determine if the put is a 
        replace or a transition to a new StructureID.

        Reduces memory use on Membuster head test (30 pages open) by ~15MB.

        Bug 21943: Avoid needless reads of temporary values in CTI code
        <https://bugs.webkit.org/show_bug.cgi?id=21943>

        If an opcode needs to load a virtual register and a previous opcode left
        the contents of that virtual register in a machine register, use the
        value in the machine register rather than getting it from memory.

        In order to perform this optimization, it is necessary to know the
        jump tagets in the CodeBlock. For temporaries, the only problematic
        jump targets are binary logical operators and the ternary conditional
        operator. However, if this optimization were to be extended to local 
        variable registers as well, other jump targets would need to be
        included, like switch statement cases and the beginnings of catch
        blocks.

        This optimization also requires that the fast case and the slow case
        of an opcode use emitPutResult() on the same register, which was chosen
        to be eax, as that is the register into which we read the first operand
        of opcodes. In order to make this the case, we needed to add some mov
        instructions to the slow cases of some instructions.

        This optimizaton is not applied whenever compileBinaryArithOp() is used
        to compile an opcode, because different machine registers may be used to
        store the final result. It seems possible to rewrite the code generation
        in compileBinaryArithOp() to allow for this optimization.

        This optimization is also not applied when generating slow cases,
        because some fast cases overwrite the value of eax before jumping to the
        slow case. In the future, it may be possible to apply this optimization
        to slow cases as well, but it did not seem to be a speedup when testing
        an early version of this patch.

        This is a 1.0% speedup on SunSpider and a 6.3% speedup on the V8
        benchmark suite.

        Simplified op_call by nixing its responsibility for moving the value of
        "this" into the first argument slot.

        Instead, the caller emits an explicit load or mov instruction, or relies
        on implicit knowledge that "this" is already in the first argument slot.
        As a result, two operands to op_call are gone: firstArg and thisVal.
        
        SunSpider and v8 tests show no change in bytecode or CTI.

        Fixed a latent bug in stack overflow checking that is now hit because
        the register layout has changed a bit -- namely: when throwing a stack
        overflow exception inside an op_call helper, we need to account for the
        fact that the current call frame is only half-constructed, and use the
        parent call frame instead.

          Stack overflow due to deeply nested parse tree doing repeated string concatentation

        Test: fast/js/large-expressions.html

        1) Code generation is recursive, so takes stack proportional to the complexity
           of the source code expression. Fixed by setting an arbitrary recursion limit
           of 10,000 nodes.

        2) Destruction of the syntax tree was recursive. Fixed by introducing a

        - fix storage leak seen on buildbot

        Some other cleanup too. The storage leak was caused by the fact
        that HashTraits<CallIdentifier>::needsDestruction was false, so
        the call identifier objects didn't get deleted.

        * profiler/CallIdentifier.h:
        
        Added a default constructor to create empty call identifiers.

        Changed the normal constructor to use const UString&
        to avoid extra copying and reference count thrash.
        
        Removed the explicit copy constructor definition, since it's what
        the compiler will automatically generate. (Rule of thumb: Either
        you need both a custom copy constructor and a custom assignment
        operator, or neither.)

        Moved the CallIdentifier hash function out of the WTF namespace;
        there's no reason to put it there.

        Changed the CallIdentifier hash function to be a struct rather than
        a specialization of the IntHash struct template. Having it be
        a specialization made no sense, since CallIdentifier is not an integer,
        and did no good.

        Removed explicit definition of emptyValueIsZero in the hash traits,
        since inheriting from GenericHashTraits already makes that false.

        Removed explicit definition of emptyValue, instead relying on the
        default constructor and GenericHashTraits.

        Removed explicit definition of needsDestruction, because we want it
        to have its default value: true, not false. This fixes the leak!

        Changed constructDeletedValue and isDeletedValue to use a line number
        of numeric_limits<unsigned>::max() to indicate a value is deleted.
        Previously this used empty strings for the empty value and null strings
        for the deleted value, but it's more efficient to use null for both.

        Initial work to reduce cost of JSNumberCell allocation

        This does the initial work needed to bring more of number
        allocation into CTI code directly, rather than just falling
        back onto the slow paths if we can't guarantee that a number

        Initial implementation only used by op_negate to make sure
        it all works.  In a negate heavy (though not dominated) test

        <rdar://problem/6326563> Crash on launch

        For Windows, export explicit functions rather than exporting data for atomicallyInitializedStaticMutex.
        
        Exporting data from a DLL on Windows requires specifying __declspec(dllimport) in the header used by
        callers, but __declspec(dllexport) when defined in the DLL implementation. By instead exporting
        the explicit lock/unlock functions, we can avoid this.

        it. This is the first step towards removing the kjs directory and
        placing files in more meaningful subdirectories of JavaScriptCore.

        Fixed Sampling Tool:
            - Made CodeBlock sampling work with CTI
            - Improved accuracy by unifying most sampling data into a single
              32bit word, which can be written / read atomically.
            - Split out three different #ifdefs for modularity: OPCODE_SAMPLING;
              CODEBLOCK_SAMPLING; OPCODE_STATS.
            - Improved reporting clarity

        for encoding samples. (This required passing the current vPC to a lot
        more functions, since the unified interface samples the current vPC.)
        Added hooks for writing the current CodeBlock* on function entry and
        after a function call, for the sake of the CodeBlock sampler. Removed
        obsolete hook for clearing the current sample inside op_end. Also removed
        the custom enum used to differentiate flavors of op_call, since the
        OpcodeID enum works just as well. (This was important in an earlier

        * VM/SamplingTool.cpp:
        (JSC::ScopeSampleRecord::sample): Only count a sample toward our total
        if we actually record it. This solves cases where a CodeBlock will
        claim to have been sampled many times, with reported samples that don't
        match.

        (JSC::SamplingTool::run): Read the current sample into a Sample helper
        object, to ensure that the data doesn't change while we're analyzing it,
        and to help decode the data. Only access the CodeBlock sampling hash
        table if CodeBlock sampling has been enabled, so non-CodeBlock sampling
        runs can operate with even less overhead.

        Fix hideous pathological case performance when looking up repatch info, bug #21727.

        When repatching JIT code to optimize we look up records providing information about
        the generated code (also used to track recsources used in linking to be later released). 
        The lookup was being performed using a linear scan of all such records.

        (1) Split up the different types of reptach information.  This means we can search them
            separately, and in some cases should reduce their size.
        (2) In the case of property accesses, search with a binary chop over the data.
        (3) In the case of calls, pass a pointer to the repatch info into the relink function.

        This adds new methods fastMallocExecutable and fastFreeExecutable

        return executable memory all the time, which will be fixed in a
        later patch.

        However in windows debug builds all executable allocations will be
        allocated on separate executable pages, which should resolve any
        remaining 2k3 issues.  Conveniently the 2k3 bot will now also fail

        Bug 21803: Fuse op_jfalse with op_eq_null and op_neq_null
        <https://bugs.webkit.org/show_bug.cgi?id=21803>

        Fuse op_jfalse with op_eq_null and op_neq_null to make the new opcodes
        op_jeq_null and op_jneq_null.

        This is a 2.6% speedup on the V8 Raytrace benchmark, and strangely also

        Change JSValuePtr from a typedef into a class. This allows us to support

        Remove casts from JSValue* to derived classes, replacing them with
        calls to inline casting functions. These functions are also a bit
        better than aidrect cast because they also do a runtime assertion.

        Move things needed by classes derived from JSValue out of the class,

        I did most of these changes by changing JSValue to not be JSValue* any

        Optimize op_call by allowing call sites to be directly linked to callees.

        For the hot path of op_call, CTI now generates a check (initially for an impossible
        value), and the first time the call is executed we attempt to link the call directly
        to the callee.  We can currently only do so if the arity of the caller and callee
        match.  The (optimized) setup for the call on the hot path is linked directly to
        the ctiCode for the callee, without indirection.
        
        Two forms of the slow case of the call are generated, the first will be executed the
        first time the call is reached.  As well as this path attempting to link the call to
        a callee, it also relinks the slow case to a second slow case, which will not continue
        to attempt relinking the call.  (This policy could be changed in future, but for not
        this is intended to prevent thrashing).

        If a callee that the caller has been linked to is garbage collected, then the link
        in the caller's JIt code will be reset back to a value that cannot match - to prevent
        any false positive matches.

        ~20% progression on deltablue & richards, >12% overall reduction in v8-tests
        runtime, one or two percent progression on sunspider.

        Bug 21541: Move RegisterFile growth check to callee

        Move the RegisterFile growth check to the callee in the common case,
        where some of the information is known statically at JIT time. There is
        still a check in the caller in the case where the caller provides too
        few arguments.

        This is a 2.1% speedup on the V8 benchmark, including a 5.1% speedup on
        the Richards benchmark, a 4.1% speedup on the DeltaBlue benchmark, and a
        1.4% speedup on the Earley-Boyer benchmark. It is also a 0.5% speedup on

        Bug 21533: Simple JavaScript code leaks StructureIDs
        <https://bugs.webkit.org/show_bug.cgi?id=21533>

        StructureID::getEnumerablePropertyNames() ends up calling back to itself
        via JSObject::getPropertyNames(), which causes the PropertyNameArray to
        be cached twice. This leads to a memory leak in almost every use of
        JSObject::getPropertyNames() on an object. The fix here is based on a
        suggestion of Sam Weinig.

        This patch also fixes every StructureID leaks that occurs while running

        Implement support for x86 Linux in CTI

        Prepare to enable CTI/WREC on supported architectures.

        Make it possible to use the CTI_ARGUMENT workaround with GCC as well
        as MSVC by fixing some preprocessor conditionals.

        Note that CTI/WREC no longer requires CTI_ARGUMENT on Linux so we
        don't actually enable it except when building with MSVC. GCC on Win32
        remains untested.

        Adapt inline ASM code to use the global symbol underscore prefix only
        on Darwin and to call the properly mangled Machine::cti_vm_throw
        symbol name depending on CTI_ARGUMENT.

        Also avoid global inclusion of the JIT infrastructure headers
        throughout WebCore and WebKit causing recompilation of about ~1500
        source files after modification to X86Assembler.h, CTI.h, WREC.h,
        which are only used deep inside JavaScriptCore.

        Bug 21459: REGRESSION (r37324): Safari crashes inside JavaScriptCore while browsing hulu.com
        <https://bugs.webkit.org/show_bug.cgi?id=21459>

        After r37324, an Arguments object does not mark an associated activation
        object. This change was made because Arguments no longer directly used
        the activation object in any way. However, if an activation is torn off,
        then the backing store of Arguments becomes the register array of the
        activation object. Arguments directly marks all of the arguments, but
        the activation object is being collected, which causes its register
        array to be freed and new memory to be allocated in its place.

        Unfortunately, it does not seem possible to reproduce this issue in a
        layout test.

          Bug 21403: use new CallFrame class rather than Register* for call frame manipulation

        Add CallFrame as a synonym for ExecState. Arguably, some day we should switch every
        client over to the new name.

        Use CallFrame* consistently rather than Register* or ExecState* in low-level code such
        as Machine.cpp and CTI.cpp. Similarly, use callFrame rather than r as its name and use
        accessor functions to get at things in the frame.

        Eliminate other uses of ExecState* that aren't needed, replacing in some cases with
        JSGlobalData* and in other cases eliminating them entirely.

        Improve the division between PropertyStorageArray and PropertyMap

        - Rework ProperyMap to store offsets in the value so that they don't

        - A Vector of deleted offsets is now needed since the storage is out of

        Bug 21364: Remove the branch in op_ret for OptionalCalleeActivation and OptionalCalleeArguments
        <https://bugs.webkit.org/show_bug.cgi?id=21364>

        Use information from the parser to detect whether an activation is
        needed or 'arguments' is used, and emit explicit instructions to tear
        them off before op_ret. This allows a branch to be removed from op_ret
        and simplifies some other code. This does cause a small change in the
        behaviour of 'f.arguments'; it is no longer live when 'arguments' is not
        mentioned in the lexical scope of the function.

        It should now be easy to remove the OptionaCalleeActivation slot in the
        call frame, but this will be done in a later patch.

        This does the minimum necessary to get the speedup. Next step in

        - "this" object in methods called on primitives should be wrapper object
        https://bugs.webkit.org/show_bug.cgi?id=21362

        I changed things so that functions which use "this" do a fast
        version of toThisObject conversion if needed. Currently we miss
        the conversion entirely, at least for primitive types. Using
        TypeInfo and the primitive check, I made the fast case bail out
        pretty fast.
        
        This is inexplicably an 1.007x SunSpider speedup (and a wash on V8 benchmarks).
     
        Also renamed some opcodes for clarity:

        The main goal in this patch is to make it easy to ask for a duplicate
        compilation, and get back a duplicate result -- same source URL, same
        debugger / profiler ID, same toString behavior, etc.
        
        The basic unit of compilation and evaluation is now SourceCode, which
        encompasses a SourceProvider, a range in that provider, and a starting
        line number.

        A SourceProvider now encompasses a source URL, and *is* a source ID,

        Bug 21123: using "arguments" in a function should not force creation of an activation object
        <https://bugs.webkit.org/show_bug.cgi?id=21123>

        Make the 'arguments' object not require a JSActivation. We store the
        'arguments' object in the OptionalCalleeArguments call frame slot. We
        need to be able to get the original 'arguments' object to tear it off
        when returning from a function, but 'arguments' may be assigned to in a
        number of ways.

        Therefore, we use the OptionalCalleeArguments slot when we want to get
        the original activation or we know that 'arguments' was not assigned a
        different value. When 'arguments' may have been assigned a new value,
        we use a new local variable that is initialized with 'arguments'. Since
        a function parameter named 'arguments' may overwrite the value of
        'arguments', we also need to be careful to look up 'arguments' in the
        symbol table, so we get the parameter named 'arguments' instead of the
        local variable that we have added for holding the 'arguments' object.

        This is a 19.1% win on the V8 Raytrace benchmark using the SunSpider
        harness, and a 20.7% win using the V8 harness. This amounts to a 6.5%
        total speedup on the V8 benchmark suite using the V8 harness.

        Improve performance of CTI on windows.

        Currently on platforms where the compiler doesn't allow us to safely
        index relative to the address of a parameter we need to actually
        provide a pointer to CTI runtime call arguments.  This patch improves
        performance in this case by making the CTI logic for restoring this
        parameter much less conservative by only resetting it before we actually
        make a call, rather than between each and every SF bytecode we generate
        code for.

        This results in a 3.6% progression on the v8 benchmark when compiled with MSVC.

        Add support for reusing temporary JSNumberCells.  This change is based on the observation
        that if the result of certain operations is a JSNumberCell and is consumed by a subsequent
        operation that would produce a JSNumberCell, we can reuse the object rather than allocating
        a fresh one.  E.g. given the expression ((a * b) * c), we can statically determine that
        (a * b) will have a numeric result (or else it will have thrown an exception), so the result
        will either be a JSNumberCell or a JSImmediate.

        This patch changes three areas of JSC:
            * The AST now tracks type information about the result of each node.
            * This information is consumed in bytecode compilation, and certain bytecode operations
              now carry the statically determined type information about their operands.
            * CTI uses the information in a number of fashions:
                * Where an operand to certain arithmetic operations is reusable, it will plant code
                  to try to perform the operation in JIT code & reuse the cell, where appropriate.
                * Where it can be statically determined that an operand can only be numeric (typically
                  the result of another arithmetic operation) the code will not redundantly check that
                  the JSCell is a JSNumberCell.
                * Where either of the operands to an add are non-numeric do not plant an optimized
                  arithmetic code path, just call straight out to the C function.

        Bug 19968: Slow Script at www.huffingtonpost.com
        <https://bugs.webkit.org/show_bug.cgi?id=19968>

        Finally found the cause of this accursed issue.  It is triggered
        by synchronous creation of a new global object from JS.  The new
        global object resets the timer state in this execution group's
        Machine, taking timerCheckCount to 0.  Then when JS returns the
        timerCheckCount is decremented making it non-zero.  The next time
        we execute JS we will start the timeout counter, however the non-zero
        timeoutCheckCount means we don't reset the timer information. This
        means that the timeout check is now checking the cumulative time
        since the creation of the global object rather than the time since
        JS was last entered.  At this point the slow script dialog is guaranteed
        to eventually be displayed incorrectly unless a page is loaded
        asynchronously (which will reset everything into a sane state).

        The fix for this is rather trivial -- the JSGlobalObject constructor
        should not be resetting the machine timer state.

        * VM/Machine.cpp:
        (JSC::Machine::Machine):
          Now that we can't rely on the GlobalObject initialising the timeout
          state, we do it in the Machine constructor.

        (JSC::Machine::stopTimeoutCheck):
          Add assertions to guard against this happening.

        * kjs/JSGlobalObject.cpp:
        (JSC::JSGlobalObject::init):
          Don't reset the timeout state.

        are negative, since they can be positive now:
        * kjs/SymbolTable.h:

        (JSC::SymbolTableEntry::pack):

        ~2% speedup on EarleyBoyer

        The idea here is to record in the StructureID whether the class
        needs a special hasInstance or if it can use the normal logic from
        JSObject. 
        
        Based on this I inlined the real work directly into
        cti_op_instanceof and put the fastest checks up front and the
        error handling at the end (so it should be fairly straightforward
        to split off the beginning to be inlined if desired).

        I only did this for CTI, not the bytecode interpreter.

        Bug 20815: 'arguments' object creation is non-optimal
        <https://bugs.webkit.org/show_bug.cgi?id=20815>

        Fix our inefficient way of creating the arguments object by only
        creating named properties for each of the arguments after a use of the
        'delete' statement. This patch also speeds up access to the 'arguments'
        object slightly, but it still does not use the array fast path for
        indexed access that exists for many opcodes.

        This is about a 20% improvement on the V8 Raytrace benchmark, and a 1.5%
        improvement on the Earley-Boyer benchmark, which gives a 4% improvement
        overall.

        Improve peformance of local variable initialisation.

        Pull local and constant initialisation out of slideRegisterWindowForCall

        Use the template hoisting technique on the RefCounted class. This reduces the code bloat due to
        non-template methods' code been copied for each instance of the template.
        The patch splits RefCounted between a base class that holds non-template methods and attributes
        and the template RefCounted class that keeps the same functionnality.

        On my Linux with gcc 4.3 for the Gtk port, this is:
        - a ~600KB save on libwebkit.so in release.
        - a ~1.6MB save on libwebkit.so in debug.

        It is a wash on Sunspider and a small win on Dromaeo (not sure it is relevant).
        On the whole, it should be a small win as we reduce the compiled code size and the only

        Improve timer accuracy for JavaScript Date object on Windows.
        
        Use a combination of ftime and QueryPerformanceCounter.
        ftime returns the information we want, but doesn't have sufficient resolution.
        QueryPerformanceCounter has high resolution, but is only usable to measure time intervals.
        To combine them, we call ftime and QueryPerformanceCounter initially. Later calls will use
        QueryPerformanceCounter by itself, adding the delta to the saved ftime.  We re-sync to
        correct for drift if the low-res and high-res elapsed time between calls differs by more
        than twice the low-resolution timer resolution.
        
        QueryPerformanceCounter may be inaccurate due to a problems with:
        - some PCI bridge chipsets (http://support.microsoft.com/kb/274323)

        Accelerate get/put_by_id by speculatively inlining a disable direct access
        into the hot path of the code, and repatch this with the correct StructureID
        and property map offset once these are known.  In the case of accesses to the
        prototype and reading the array-length a trampoline is genertaed, and the
        branch to the slow-case is relinked to jump to this.

        By repatching, we mean rewriting the x86 instruction stream.  Instructions are
        only modified in a simple fasion - altering immediate operands, memory access
        deisplacements, and branch offsets.
        
        For regular get_by_id/put_by_id accesses to an object, a StructureID in an
        instruction's immediate operant is updateded, and a memory access operation's
        displacement is updated to access the correct field on the object.  In the case
        of more complex accesses (array length and get_by_id_prototype) the offset on
        the branch to slow-case is updated, to now jump to a trampoline.

        Bug 20821: Cache property transitions to speed up object initialization
        https://bugs.webkit.org/show_bug.cgi?id=20821

        Implement a transition cache to improve the performance of new properties
        being added to objects.  This is extremely beneficial in constructors and
        shows up as a 34% improvement on access-binary-trees in SunSpider (0.8%

        - enable polymorphic inline caching of properties of primitives
        
        1.012x speedup on SunSpider.

        We create special structure IDs for JSString and
        JSNumberCell. Unlike normal structure IDs, these cannot hold the
        true prototype. Due to JS autoboxing semantics, the prototype used
        when looking up string or number properties depends on the lexical
        global object of the call site, not the creation site. Thus we
        enable StructureIDs to handle this quirk for primitives.
        
        Everything else should be straightforward.

        transition based on property name and attribute pairs, instead of just
        property name.

        Bug 20694: Slow Script error pops up when running Dromaeo tests

        Correct error in timeout logic where execution tick count would
        be reset to incorrect value due to incorrect offset and indirection.
        Codegen for the slow script dialog was factored out into a separate
        method (emitSlowScriptCheck) rather than having multiple copies of
        the same code.  Also added calls to generate slow script checks

        Jump through the necessary hoops required to make MSVC cooperate with SFX

        We now explicitly declare the calling convention on all cti_op_* cfunctions,
        and return int instead of bool where appropriate (despite the cdecl calling
        convention seems to state MSVC generates code that returns the result value
        through ecx).  SFX behaves slightly differently under MSVC, specifically it
        stores the base argument address for the cti_op_* functions in the first
        argument, and then does the required stack manipulation through that pointer.
        This is necessary as MSVC's optimisations assume they have complete control
        of the stack, and periodically elide our stack manipulations, or move
        values in unexpected ways.  MSVC also frequently produces tail calls which may
        clobber the first argument, so the MSVC path is slightly less efficient due
        to the need to restore it.

        Zero-cost exception handling.  This patch takes the exception checking
        back of the hot path.  When an exception occurs in a Machine::cti*
        method, the return address to JIT code is recorded, and is then
        overwritten with a pointer to a trampoline routine.  When the method
        returns the trampoline will cause the cti_vm_throw method to be invoked.

        cti_vm_throw uses the return address preserved above, to discover the
        vPC of the bytecode that raised the exception (using a map build during
        translation).  From the VPC of the faulting bytecode the vPC of a catch
        routine may be discovered (unwinding the stack where necesary), and then
        a bytecode address for the catch routine is looked up.  Final cti_vm_throw
        overwrites its return address to JIT code again, to trampoline directly
        to the catch routine.
        
        cti_op_throw is handled in a similar fashion.

        Support for exception unwinding the stack.
        
        Once upon a time, Sam asked me for a bettr ChangeLog entry.  The return address
        is now preserved on entry to a JIT code function (if we preserve lazily we need
        restore the native return address during exception stack unwind).  This takes
        the number of regressions down from ~150 to 19.

        A temporary value in the slow path of op_bitand was being stored in edx, but was
        being clobbered by emitGetPutArg before we used it.  To fix this, emitGetPutArg
        now takes a third argument that specifies the scratch register to use when loading
        from memory.  This allows us to avoid clobbering the temporary in op_bitand.

          JavaScriptCore string manipulation spends too much time in memcpy

        1.011x as fast on SunSpider overall
        1.028x as fast on SunSpider string tests

        For small strings, use a loop rather than calling memcpy. The loop can
        be faster because there's no function call overhead, and because it can
        assume the pointers are aligned instead of checking that. Currently the
        threshold is set at 20 characters, based on some testing on one particular
        computer. Later we can tune this for various platforms by setting
        USTRING_COPY_CHARS_INLINE_CUTOFF appropriately, but it does no great harm
        if not perfectly tuned.

        point, since that's the common case.
        (KJS::stringProtoFuncCharCodeAt): Ditto.
        (KJS::stringProtoFuncMatch): Adopted jsSubstring and jsEmptyString.
        (KJS::stringProtoFuncSlice): Adopted jsSubstring and
        jsSingleCharacterSubstring. Also got rid of some unneeded locals and
        removed unneeded code to set the length property of the array, since it
        is automatically updated as values are added to the array.
        (KJS::stringProtoFuncSplit): Adopted jsEmptyString.
        (KJS::stringProtoFuncSubstr): Adopted jsSubstring.
        (KJS::stringProtoFuncSubstring): Ditto.

        * kjs/collector.cpp:
        (KJS::Heap::collect): Added a call to mark SmallStrings.

        * kjs/ustring.cpp:
        (KJS::UString::expandedSize): Made this a static member function since
        it doesn't need to look at any data members.
        (KJS::UString::expandCapacity): Use a non-inline function, makeNull, to
        set the rep to null in failure cases. This avoids adding a PIC branch for
        the normal case when there is no failure.
        (KJS::UString::expandPreCapacity): Ditto.
        (KJS::UString::UString): Ditto.
        (KJS::concatenate): Refactored the concatenation constructor into this
        separate function. Calling the concatenation constructor was leading to
        an extra branch because of the in-charge vs. not-in-charge versions not
        both being inlined, and this was showing up as nearly 1% on Shark. Also
        added a special case for when the second string is a single character,
        since it's a common idiom to build up a string that way and we can do
        things much more quickly, without involving memcpy for example. Also
        adopted the non-inline function, nullRep, for the same reason given for
        makeNull above.
        (KJS::UString::append): Adopted makeNull for failure cases.
        (KJS::UString::operator=): Ditto.
        (KJS::UString::toDouble): Added a special case for converting single
        character strings to numbers. We're doing this a ton of times while
        running the base64 test.
        (KJS::operator==): Added special cases so we can compare single-character
        strings without calling memcmp. Later we might want to special case other
        short lengths similarly.
        (KJS::UString::makeNull): Added.
        (KJS::UString::nullRep): Added.
        * kjs/ustring.h: Added declarations for the nullRep and makeNull. Changed
        expandedSize to be a static member function. Added a declaration of the
        concatenate function. Removed the concatenation constructor. Rewrote
        operator+ to use the concatenate function.

        <rdar://problem/6150322> In Gmail, a crash occurs at KJS::Machine::privateExecute() when applying list styling to text after a quote had been removed
        <https://bugs.webkit.org/show_bug.cgi?id=20386>

        This crash was caused by "depth()" incorrectly determining the scope depth 
        of a 0 depth function without a full scope chain.  Because such a function
        would not have an activation the depth function would return the scope depth
        of the parent frame, thus triggering an incorrect unwind.  Any subsequent 
        look up that walked the scope chain would result in incorrect behaviour,
        leading to a crash or incorrect variable resolution.  This can only actually
        happen in try...finally statements as that's the only path that can result in
        the need to unwind the scope chain, but not force the function to need a
        full scope chain.

        The fix is simply to check for this case before attempting to walk the scope chain.

        JSStringRef is created context-free, but can get linked to one via an identifier table,
        breaking an implicit API contract.

        Made JSStringRef point to OpaqueJSString, which is a new string object separate from UString.

        * API/APICast.h: Removed toRef/toJS conversions for JSStringRef, as this is no longer a
        simple typecast.

        * API/JSObjectRef.cpp:
        (OpaqueJSPropertyNameArray::OpaqueJSPropertyNameArray): Changed OpaqueJSPropertyNameArray to
        hold JSStringRefs. This is necessary to avoid having to construct (and leak) a new instance
        in JSPropertyNameArrayGetNameAtIndex(), now that making a JSStringRef is not just a typecast.
