Currently in OpenACC 'kernels' decomposition, there is special handling of 'GOMP_MAP_FORCE_TOFROM', documented to be done to avoid "internal compiler errors in later passes". For performance reasons, the current repetitive to/from device copying for every region is not ideal, compared to using 'present' clauses, as done for almost all other 'GOMP_MAP_*'. Also, the current special handling (incomplete, evidently) is the reason for the PR104892 misbehavior. For PR100280 etc. we've resolved all such known ICEs -- removing the special handling for 'GOMP_MAP_FORCE_TOFROM' now resolves PR104892.
