    c++: template partial instantiation mismatch [PR 99528]

    This turned out to be an existing problem, which had been hidden by
    other bugs.  Templated members of templated classes can end up
    instantiating the template itself, and we were not handling the
    mergeableness of that correctly.

            PR c++/99528
            gcc/cp/
            * module.cc (enum merge_kind): Delete MK_type_tmpl_spec,
            MK_decl_tmpl_spec.
            (trees_in::decl_value): Adjust add_mergeable_specialization call.
            (trees_out::get_merge_kind): Adjust detecting a partial template
            instantiation.
            (trees_out::key_mergeable): Adjust handling same.
            (trees_in::key_mergeabvle): Likewise.
