Kang Zhang 513976df2e [PowerPC] Ignore implicit register operands for MCInst 
Summary:
When doing the conversion: MachineInst -> MCInst, we should ignore the
implicit operands, it will expose more opportunity for InstiAlias.

Nemanja Ivanovic ecd8435483 [NFC][PowerPC] Fix register class for patterns using XXPERMDIs 
There are a few patterns where we use a superclass for inputs to this
instruction rather than the correct class. This can sometimes lead to
unncessary copies.

Nemanja Ivanovic 1461fb6e78 [PowerPC] Exploit single instruction load-and-splat for word and doubleword 
We currently produce a load, followed by (possibly a move for integers and) a
splat as separate instructions. VSX has always had a splatting load for
doublewords, but as of Power9, we have it for words as well. This patch just
exploits these instructions.
