Akim Demaille a7e46f6e41 C++: don't issue the definition of symbol_type when not used ...

Currently, in glr.cc, we emit the definitions of basic_symbol and
symbol_type, although there are not used.

* data/c++.m4 (b4_public_types_declare): Extract these definitions from
here, and move them...
(b4_symbol_type_declare): here.
(b4_public_types_declare): Also remove the definition of the symbol
constructors.
* data/lalr1.cc (b4_shared_declarations): Adjust: call
b4_symbol_type_declare and b4_symbol_constructor_declare.
