(goacc_exit_data_internal): Support detach operations and
GOMP_MAP_STRUCT.
(GOACC_enter_exit_data): Handle initial GOMP_MAP_STRUCT or
GOMP_MAP_FORCE_PRESENT in finalization detection code. Handle
attach/detach in enter/exit data detection code.
* target.c (gomp_map_vars_existing): Initialise do_detach field of
