Log:
[Power9] Implement new vsx instructions: load, store instructions for vector and scalar
We follow the comments mentioned in http://reviews.llvm.org/D16842#344378 to
implement this new patch.
This patch implements the following vsx instructions:
Vector load/store:
lxv lxvx lxvb16x lxvl lxvll lxvh8x lxvwsx
stxv stxvb16x stxvh8x stxvl stxvll stxvx
Scalar load/store:
lxsd lxssp lxsibzx lxsihzx
stxsd stxssp stxsibx stxsihx
21 instructions
