[PATCH] D122482: [X86] combineADC - fold ADC(C1,C2,Carry) -> ADC(0,C1+C2,Carry)

I was just surprised to see that the last four lines didn't swap the BT and the zeroing of EDX. Maybe this is a separate problem. This seems like the natural output of the last four lines of the example above:

  xor %edx,%edx
  bt $0x2a,%rsi
  adc $0x2,%edx
  cmp $0x1,%edi
