    openmp: Reject invalid forms of C++ #pragma omp atomic compare [PR106448]

    The allowed syntaxes of atomic compare don't allow ()s around the condition
    of ?:, but we were accepting it in one case for C++.

    Fixed thusly.

            * parser.cc (cp_parser_omp_atomic): For simple cast followed by
            CPP_QUERY token, don't try cp_parser_binary_operation if compare
            is true.
