Thomas Schwinge a07b8f4fb7 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.
