Open for review, comments welcome:
https://github.com/lazy-fortran/gcc/pull/33
This carries attachment 63146 forward. The duplicate-key compensation
in goacc_enter_data_internal is narrowed to GOMP_MAP_TO_PSET groups:
each descriptor key is counted once for a new TO_PSET group and the
extra refcount added for its pointer entry is cancelled, so repeated
alloc/enter/exit/deallocate cycles no longer leave a stale mapping.
Includes a runtime test with reallocation cycles. The reproducer fails
before and passes after on a real NVPTX device; check-fortran and the
libgomp suites are clean.
