Akim Demaille fd37eb057e yysymbol_type_t: always assign an enumerator ...

Currently we define enumerators only for symbols that have an
identifier.  That rules out tokens such as '+', and nonterminals such
as foo-bar and foo.bar.  As a consequence we are taking chances: the
compiler might compile yysymbol_type_t as too small an integral type
for some symbol codes.

* data/skeletons/bison.m4 (b4_symbol_sid): Forge a unique symbol
identifier for symbols that don't have an ID.
