instructions to avoid copies, because TwoAddressInstructionPass also does this optimization. The scheduler's version didn't account for live-out values, which resulted in spurious commutes and missed opportunities. Now, TwoAddressInstructionPass handles all the opportunities, instead of just those that the scheduler missed. The result is usually the same, though there are occasional trivial differences resulting from the avoidance of spurious commutes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61611 91177308-0d34-0410-b5e6-96231b3b80d8
