[PATCH] D60940: [X86] Don't form masked instructions if the operation has an additional user.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

If we are happy with the assumption that a masked move is always as cheap or cheaper than any other masked op (we may want to explicitly state that at the vselect_mask def at the top of X86InstrAVX512.td), I think this makes sense but I don't envy the job of fixing all these tests and adding more relevant ones.......
