95af9b33 - [PowerPC] Do not rely on MachineSink threshold to optimize CR spilling

[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.
