Sean Fertile 1c4109b4c2 [PPC] Add intrinsics for vector extract word and vector insert word.

Nemanja Ivanovic 6e7879c5e6 [Power9] Add exploitation of non-permuting memory ops 
This patch corresponds to review:
https://reviews.llvm.org/D19825

The new lxvx/stxvx instructions do not require the swaps to line the elements
up correctly. In order to select them over the lxvd2x/lxvw4x instructions which
require swaps, the patterns for the old instruction have a predicate that
ensures they won't be selected on Power9 and newer CPUs.

Nemanja Ivanovic d5deb4896c Fix code-gen crash on Power9 for insert_vector_elt with variable index (PR30189) 
This patch corresponds to review:
https://reviews.llvm.org/D24021

In the initial implementation of this instruction, I forgot to account for
variable indices. This patch fixes PR30189 and should probably be merged into
3.9.1 (I'll open a bug according to the new instructions).

Nemanja Ivanovic f0407e3902 The test case I added is PowerPC specific but I accidentally 
had it in the wrong directory. Moved it to CodeGen/PowerPC.

Sorry about the noise.
