[X86] combineAddOrSubToADCOrSBB - Fold ADD/SUB + (AND(SRL(X,Y),1) -> ADC/SBB+BT(X,Y) (REAPPLIED)

As suggested on PR35908, if we are adding/subtracting an extracted bit, attempt to use BT instead to fold the op and use a ADC/SBB op.

Reapply with extra type legality checks - LowerAndToBT was originally only used during lowering, now that it can occur earlier we might encounter illegal types that we can either promote to i32 or just bail.
