shuffle could be skipped. The check is invalid because the loop index i doesn't correspond to the element actually inserted. The correct check is already done a few lines earlier, for whether the element is already in the right spot, so this shouldn't have any effect on the codegen for code that was already correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52486 91177308-0d34-0410-b5e6-96231b3b80d8
