  -----------
  [ARM] Transfer memory operands for VLDn

We create MMO's for the VLDn/VSTn intrinsics in ARMTargetLowering::
getTgtMemIntrinsic, but they do not currently make it ll the way through
ISel.  This changes that in the various places it needs changing, making
sure that the MMO is propagate through to the final instruction. This
can help in scheduling, not treating the VLD2/VST2 as a scheduling
barrier.
