It never makes sense for a GOMP_MAP_ATTACH_DETACH mapping to survive
beyond gimplify.c, and with OpenMP making use of that mapping type too
now alongside OpenACC, there are cases where it was making it through
to omp-low.c.  This patch rewrites such mappings to GOMP_MAP_ATTACH or
GOMP_MAP_DETACH unconditionally for both OpenACC and OpenMP, in cases
where it hasn't otherwise been handled already in the preceding code.

2021-05-11  Julian Brown  <julian@codesourcery.com>

gcc/
	* gimplify.c (gimplify_scan_omp_clauses): Remove OpenACC-only
	condition for changing GOMP_MAP_ATTACH_DETACH to GOMP_MAP_ATTACH or
	GOMP_MAP_DETACH.  Use detach for OMP_TARGET_EXIT_DATA also.
