    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.
