Swap PPC isel operands to allow for 0-folding The PPC isel instruction can fold 0 into the first operand (thus eliminating the need to materialize a zero-containing register when the 'true' result of the isel is 0). When the isel is fed by a bit register operation that we can invert, do so as part of the bit-register-operation peephole routine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202469 91177308-0d34-0410-b5e6-96231b3b80d8
