Lei Huang 74b05fb18e [PowerPC] Custom lower known CR bit spills 
For known CRBit spills, CRSET/CRUNSET, it is more efficient to load and spill
the known value instead of extracting the bit.

eg. This sequence is currently used to spill a CRUNSET:
    crclr   4*cr5+lt
    mfocrf  r3,4
    rlwinm  r3,r3,20,0,0
    stw     r3,132(r1)

This patch custom lower it to:
    li  r3,0
    stw r3,132(r1)
