Changes in directory llvm/lib/Target/PowerPC:

PPC32ISelPattern.cpp updated: 1.161 -> 1.162
---
Log message:

Remove some dead cases.
Emit the indcall sequence as:

mtctr inreg
mr R12, inreg
btctr

If inreg and R12 aren't coallesced, this reduces the odds of having the mtctr 
and btctr in the same dispatch group.  :)
