[Graham Yiu via Phabricator via llvm-commits]

gyiu added a comment.

- Refactored NFCs to another patch to be committed.
- Made changes to remove restriction on only recognizing shuffles of halfword element 3 (4 in LE mode) when both input vectors are the same vector.  That is, we can now recognize all single element shuffles in this situation.
