This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@358546 91177308-0d34-0410-b5e6-96231b3b80d8	2019-04-17 02:12:23 +00:00
Craig Topper	ccba49dfc2	[InstCombine] Teach select01 helper of foldSelectIntoOp to handle vector splats ...
