  Log Message:
  -----------
  [PowerPC] Do not rely on MachineSink threshold to optimize CR spilling

spill_p0_setb.ll and knowCRBitSpill.ll rely on a probability threshold
in MachineSink to pull down CRSET/CRUNSET. It's worth to do so anyway
and let register allocation decide otherwise.
Additionally, make the interface accept a const MI.
