[PATCH] D13161: [PATCH, PR24373] Combine shifts for x86

[Simon Pilgrim via llvm-commits]

RKSimon added a comment.

I do wonder if this could be beneficial for other targets - possibly moving this to DAGCombiner and using a a test against isExtFree() or similar?

Also, please can you add tests against the load-execute versions movs*?
