Craig Topper 950ca192f6 [X86] Lower ISD::UADDO to use the Z flag instead of C flag when the RHS is a constant 1 to encourage INC formation. 
Summary:
Add an additional combine to combineCarryThroughADD to reverse it back to the C flag to avoid regressions.

I believe this catches the cases that D57547 got.
