	* hsa.h (is_a_helper): New overload for hsa_op_immed for
	hsa_op_with_type operands.
	(hsa_unsigned_type_for_type): Declare.
	* hsa.c (hsa_unsigned_type_for_type): New function.
	* hsa-gen.c (gen_hsa_binary_operation): Use hsa_unsigned_type_for_type.
	(gen_hsa_insns_for_operation_assignment): Satisfy constrains of
	the finalizer.  Do not emit extra move.
