[PATCH] D56544: [X86][AARCH64] Improve ISD::ABS support

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

@efriedma I've reduced the aarch64 side to just the test codegen change. I think that should be enough to let this patch continue and any aarch64 side perf tweaks can be done in parallel?
