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. llvm-svn: 52486
