rs6000: Workaround for PR98092
The bcdinvalid_<mode> RTL instruction uses the "unordered" comparison,
which cannot be used if we have -ffinite-math-only. We really need
CCMODEs that describe what bits in a CR field are set by other insns
than just comparisons, but that is a lot more surgery, and it is stage 4
now. This patch does a simple workaround.
