[og10] Rewrite GOMP_MAP_ATTACH_DETACH mappings unconditionally

It never makes sense for a GOMP_MAP_ATTACH_DETACH mapping to survive
beyond gimplify.c, so this patch rewrites such mappings to GOMP_MAP_ATTACH
or GOMP_MAP_DETACH unconditionally (rather than checking for a list
of types of OpenACC or OpenMP constructs), in cases where it hasn't
otherwise been done already in the preceding code.

gcc/
	* gimplify.c (gimplify_scan_omp_clauses): Simplify condition
	for changing GOMP_MAP_ATTACH_DETACH to GOMP_MAP_ATTACH or
	GOMP_MAP_DETACH.
