	* hsa-gen.c (get_memory_order_name): Mask with MEMMODEL_BASE_MASK.
	Use short lowercase names.
	(get_memory_order): Mask with MEMMODEL_BASE_MASK.  Support
	MEMMODEL_CONSUME with acquire semantics and MEMMODEL_SEQ_CST with
	acq_rel one.  Protect warning agains segfaults if
	get_memory_order_name returns NULL.
	(gen_hsa_ternary_atomic_for_builtin): Support with MEMMODEL_SEQ_CST
	with release semantics.  Do not warn if get_memory_order already did.
	(gen_hsa_insns_for_call): Support with MEMMODEL_SEQ_CST with acquire
	semantics.  Fix check for relaxed or acquire semantics.  Do not warn
	if get_memory_order already did.
