  /* Support for OpenMP 4.5 monotonic and nonmonotonic schedule modifiers.
   * Since we need to distinguish the three possible cases (no modifier,
   * monotonic modifier, nonmonotonic modifier), we need separate bits for
   * each modifier. The absence of monotonic does not imply nonmonotonic,
   * especially since 4.5 says that the behaviour of the "no modifier" case
   * is implementation defined in 4.5, but will become "nonmonotonic" in 5.0.
   *
   * Since we're passing a full 32 bit value, we can use a couple of high
   * bits for these flags; out of paranoia we avoid the sign bit.
   *
   * These modifiers can be or-ed into non-static schedules by the compiler
   * to pass the additional information. They will be stripped early in the
   * processing in __kmp_dispatch_init when setting up schedules, so
   * most of the code won't ever see schedules with these bits set.
