[PATCH] Implement the vpopcnt instructions for POWER8

[Kit Barton]

Addressed Hal's comments.
One additional change - I realized the vpopcnt instructions were predicated on HasAltivec, so it would be possible to generate them when they are not available. I added a new HasP8Altivec predicate at the end of PPCInstrAltivec.td and moved the definitions of the vpopcnt* instructions to there.
