    replace atoi with stroul in c_parser_gimple_parse_bb_spec [PR114541]

    The full treatment of these invalid values was considered out of
    scope for this patch.

            PR c/114541
            * gimple-parser.cc (c_parser_gimple_parse_bb_spec):
            Use strtoul with ERANGE check instead of atoi to avoid UB
            and detect invalid __BB#.
