mmix.h (LIBCALL_VALUE): Use MMIX_RETURN_VALUE_REGNUM, not MMIX_OUTGOING_RETURN_VALUE_REGNUM.

	* config/mmix/mmix.h (LIBCALL_VALUE): Use
	MMIX_RETURN_VALUE_REGNUM, not MMIX_OUTGOING_RETURN_VALUE_REGNUM.
	(FUNCTION_VALUE_REGNO_P): Similar, but move code to...
	* config/mmix/mmix.c (mmix_function_value_regno_p): New.
	* config/mmix/mmix-protos.h: Remove needless ifdefs on TREE_CODE
	and RTX_CODE.
	(mmix_function_value_regno_p): Declare.
