	PR target/71869
	* config/rs6000/rs6000.c (rs6000_generate_compare): Rework
	__float128 support when we don't have hardware support, so that
	the IEEE built-in functions like isgreater, first call __unordkf3
	to make sure neither operand is a NaN, and if both operands are
	ordered, do the normal comparison.
