[CGP] move overflow intrinsic insertion to common location; NFCI

We need to enhance the uaddo matching to handle special-cases
as seen in PR40486 and PR31754. That means we won't necessarily
have a def-use pattern, so we'll need to check dominance to
determine where to place the intrinsic (as we already do for
usubo). This preliminary patch is just rearranging the code,
so the planned follow-up to improve uaddo will be more clear.
