C++ parser: Should we get rid of cp_parser_declarator_id?

If we make it "static inline", would not we gain the same efficiency
and preserve the comments and all that?  In general, the methodoly
seems to have a function for each non-terminal -- following a long
tradition of recursive descent parser -- and maintaining that
principle is helpful for code clarity.
