* 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.

* gcc.target/powerpc/float128-cmp.c: New test to make sure that
IEEE built-in functions handle quiet and signalling NaNs
correctly.
