        * name-lookup.c (pushdecl_maybe_friend): Return early on
        error_mark_node.
        * except.c (expand_start_catch_block): Use error_mark_node instead
        of NULL_TREE for invalid decls.
        * parser.c (cp_parser_exception_declaration): Return error_mark_node
        on invalid catch parameter. Simplify.
