[PATCH] D19825: Power9 - Add exploitation of vector load and store that do not require swaps

[Nemanja Ivanovic via llvm-commits]

Herald added a subscriber: nemanjai.

Removed the additional "AddedComplexity" clause to favour new loads/stores over the old ones.
Predicated the old loads and stores on previous ISA levels (prior to 3.0).
Provided a subtarget method for querying whether the target needs swaps for VSX memory operations.
