This reverts commit r216698 which reverted r216523 and r216598. We would attempt to perform the transformation even if the match() failed because, as a side effect, it would set V. This would trick us into believing that we correctly found a place to correctly apply the transform. An additional test case was added to getelementptr.ll so that we might not regress in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216890 91177308-0d34-0410-b5e6-96231b3b80d8
