    c++: Don't try to parse a function declaration as deduction guide [PR97663]

    While these function declarations have NULL decl_specifiers->type,
    they have still type specifiers specified from which the default int
    in the return type is added, so we shouldn't try to parse those as
    deduction guides.

            * parser.c (cp_parser_init_declarator): Don't try to parse
            C++17 deduction guides if there are any type specifiers even when
            type is NULL.
