openacc: GOMP_MAP_ATTACH handling in find_group_last
Arrange for GOMP_MAP_ATTACH to be grouped together with a preceding
GOMP_MAP_TO_PSET or other "to" data movement clause, except in cases
where an explicit "attach" clause is used.

include/
* gomp-constants.h (gomp_map_kind): Update comment for GOMP_MAP_TO_PSET.
libgomp/
* oacc-mem.c (find_group_last): Group data-movement clauses
(GOMP_MAP_TO_PSET, GOMP_MAP_TO, etc.) together with a subsequent
GOMP_MAP_ATTACH. Allow standalone GOMP_MAP_ATTACH also.
