+ Use negative line numbers.
+ * src/muscle_tab.c (muscle_percent_define_default): Likewise.
+ * src/location.c (location_print): If line for a boundary is negative,

Use b4_type_names for the union type.
- The union used to compute the size of the variant used to iterate over the
- type of all the symbols, with a lot of redundancy. Now iterate over the
- lists of symbols having the same type-name.

Define the "identifier" of a symbol.
- Symbols may have several string representations, for instance if they
- have an alias. What I call its "id" is a string that can be used as
- an identifier. May not exist.
-
- Currently the symbols which have the "tag_is_id" flag set are those that
- don't have an alias. Look harder for the id.

Introduce make_symbol.
- make_symbol provides a means to construct a full symbol (kind, value,
- location) in a single shot. It is meant to be a Symbol constructor,
- parameterized by the symbol kind so that overloading would prevent
- incorrect kind/value pairs. Unfortunately parameterized constructors do
- not work well in C++ (unless the parameter also appears as an argument,
- which is not acceptable), hence the use of a function instead of a
- constructor.

Rely on the state stack to display reduction traces.

Fuse the three stacks into a single one.
- In order to make it easy to perform benchmarks to ensure that there are no
- performance loss, lalr1.cc is forked into lalr1-fusion.cc. Eventually,
- lalr1-fusion.cc will replace lalr1.cc.
- Meanwhile, to make sure that lalr1-fusion.cc is correctly exercized by the
- test suite, the user must install a symbolic link from lalr1.cc to it.

- Instead of having three stacks (state, value, location), use a stack
- of triples. This considerably simplifies the code (and it will be
- easier not to require locations as currently does the C++ parser),
- and also gives a 10% speedup according to etc/bench (probably mainly since
- memory allocation is done once instead of three times).

Use variants to support objects as semantic values.
- This patch was inspired by work by Michiel De Wilde. But he used Boost
- variants which (i) requires Boost on the user side, (ii) is slow, and
- (iii) has useless overhead (the parser knows the type of the semantic value
- there is no reason to duplicate this information as Boost.Variants do).
