[PATCH] D34160: [Power9] Exploit vinserth instruction

[Graham Yiu via Phabricator via llvm-commits]

Changed my mind, removed changes related to this comment:

"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."

Will use a different patch to remove the restriction instead, as the contents of this patch is still functionally correct.
