[PATCH] [AArch64] Adds SchedRW lists to NEON instructions.

[Dave Estes]

  Hey Folks,

  This is a follow-up patch to my last patch (D2829 Adds Cortex-A53 and Cortex-A57 subtargets). It annotates the rest of the AArch64 instructions with default SchedRW lists and fixes a few of the annotations from the previous patch. A new lit test was added and this patch passed a make check-all.
