/* 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. */
