        * pt.c (finish_member_template_decl): If the type in a TYPE_DECL
        is error_mark_node, return an error early.
        (find_parameter_packs_r): Pass the pointer set along to recursive
        calls of cp_walk_subtrees; don't try to manage the pointer set
        ourselves.
        (uses_parameter_packs): Pass the pointer set to cp_walk_tree.
        (make_pack_expansion): Ditto.
        (check_for_bare_parameter_packs): Ditto. Also, don't bother taking
        a second pass through the tree with find_parameter_packs_r; that
        second pass no longer does anything.
        (push_template_decl_real): If we have an erroneous declaration,
        set its type to error_mark_node before returning an error.
