3435 <rdar://problem/4433496> Need a way to mark libraries usable by dynamic linker but unusable by static linker
3436 * src/Options.cpp: allow -client_name to be used with main executables
3437 * src/ld.cpp: generalize -allowable_client. Any dylib can now restrict who can link against it. As a convention
3438 linking with -allowable_client '!' will mean no one can statically link with the dylib. It can still be loaded
3439 dynamically, or by any existing clients, but no new clients can link with it.
3440 * unit-tests/test-cases/allowable-client/Makefile: enable previously commented out test cases. Add test cases
3441 of a dylib that allows no clients and just one client
