/* Remapping of nonmonotonic runtime schedule and maybe nonmonotonic runtime
   schedule loop entrypoints (the used by GCC 9 and later for runtime
   schedule without monotonic or nonmonotonic modifiers).
   RHEL 7 libgomp only implements the GOMP*loop*runtime* entrypoints without
   nonmonotonic in the names, which always implement monotonic scheduling,
   but the library doesn't implement any other scheduling, even in GCC 9
   and monotonic scheduling is a valid implementation of non-monotonic
   scheduling.  */
