Extend gengtype (and gtype.state reading/writing) so that it is able to
parse base classes in simple cases, and only attempt to do it for
GTY-marked types.

        * gengtype-parse.c (require_without_advance): New.
        (type): For GTY-marked types that are not GTY((user)), parse any
        base classes, requiring them to be single-inheritance, and not
        be templates.  For non-GTY-marked types and GTY((user)),
        continue to skip over any C++ inheritance specification.
        * gengtype-state.c (state_writer::write_state_struct_type):
        Write base class of type (if any).
        (read_state_struct_type): Read base class of type (if any).
        * gengtype.c (new_structure): Add a "base_class" parameter.
        (create_optional_field_): Update for new parameter to
        new_structure.
        (adjust_field_rtx_def): Likewise.
        (adjust_field_tree_exp): Likewise.
        * gengtype.h (struct type): Add "base_class" field to the s
        union field.
        (new_structure): Add "base" parameter.

This is OK.
