affinity-fmt.c: Include inttypes.h if HAVE_INTTYPES_H.

* affinity-fmt.c: Include inttypes.h if HAVE_INTTYPES_H.
	(gomp_display_affinity): Use __builtin_choose_expr to handle
	properly handle argument having integral, or pointer or some other
	type.  If inttypes.h is available and PRIx64 is defined, use PRIx64
	with uint64_t type instead of %llx and unsigned long long.
