Just double checked, this is the full omp related options currently in use:

  "-fopenmp"
  "-fopenmp-version=31"
  "-fopenmp-version=31"
  "-fopenmp-cuda-parallel-target-regions"

We saw a huge number of `DECLS_TO_CHECK_FOR_DEFERRED_DIAGS` records. I don't know if this has anything to do with omp version being 31, since prior 5.0, everything is available on host and `getEmissionStatus` would return `FunctionEmissionStatus::Unknown` in this case.
