[PATCH] D121320: X86ISelDAGToDAG: Transform TEST + MOV64ri to SHR + TEST

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

There was a question about the effect of extra uses within this pattern, so I added some tests to show the effect on the existing code:

Can you add some tests similar to those, so we'll have more visibility into what this change will do?
