    OpenACC 'kernels' decomposition: resolve wrong-code cases unless manually
making certain variables addressable [PR100280, PR104892]

    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.
