Roman Lebedev b4d8cd227c [DAGCombine][ARM][X86] (sub Carry, X) -> (addcarry (sub 0, X), 0, Carry) fold ...

Summary:
`DAGCombiner::visitADDLikeCommutative()` already has a sibling fold:
`(add X, Carry) -> (addcarry X, 0, Carry)`

This fold, as suggested by @efriedma, helps recover from //some//
of the regressions of D62266
