Target Milestone: ---
As made apparent by the 'dg-xfail-run-if' added, r279621 "OpenACC reference
count overhaul" regressed the 'libgomp.oacc-c-c++-common/pr92843-1.c' test
case:
pr92843-1.exe: [...]/libgomp.oacc-c-c++-common/pr92843-1.c:26:
verify_array: Assertion `array[i] == value' failed.
There are patches to cure this:

"Don't copy back vars mapped with acc_map_data", but these have issues on their
own (cause other regressions).
