        can use the first argument to create_option.

        token type.  Don't call find_structure; return the tag as a string.

        or scalar_nonchar as appropriate.

        to use string_type.
        (throughout): Use scalar_nonchar instead of calling create_scalar_type,
        whenever possible.
        (main): Initialize scalar_char and scalar_nonchar before calling
        gen_rtx_next.
        * gengtype-lex.l: Adjust for removal of second argument to

        * gengtype-yacc.y: Type of SCALAR is string.  Call
        create_scalar_type from type:SCALAR rule.  Adjust for removal of
        second argument to create_scalar_type.

        * gengtype-yacc.y (VEC_TOKEN): New token type.
        (type): Add a production for VEC(a,b).
        * Makefile.in: Update dependencies.

        * gengtype-lex.l: Remove rules for parsing pointer-to-function
        typedefs that use the old PARAMS macro.
