This part defines GOMP_MAP_DYNAMIC_ARRAY_* symbols in include/gomp-constants.h.
Basically use the next bit to define GOMP_MAP_FLAG_SPECIAL_3 to achieve this
purpose.

Thanks,
Chung-Lin Tang

	include/
	* gomp-constants.h (GOMP_MAP_FLAG_SPECIAL_3): Define.
	(enum gomp_map_kind): Add GOMP_MAP_DYNAMIC_ARRAY,
	GOMP_MAP_DYNAMIC_ARRAY_TO, GOMP_MAP_DYNAMIC_ARRAY_FROM,
	GOMP_MAP_DYNAMIC_ARRAY_TOFROM, GOMP_MAP_DYNAMIC_ARRAY_FORCE_TO,
	GOMP_MAP_DYNAMIC_ARRAY_FORCE_FROM, GOMP_MAP_DYNAMIC_ARRAY_FORCE_TOFROM,
	GOMP_MAP_DYNAMIC_ARRAY_ALLOC, GOMP_MAP_DYNAMIC_ARRAY_FORCE_ALLOC,
	GOMP_MAP_DYNAMIC_ARRAY_FORCE_PRESENT.
	(GOMP_MAP_DYNAMIC_ARRAY_P): Define.
