151a80bb - [TargetLowering][ExpandABD] Prefer selects over usubo if we do the same for ucmp (#159889)

[TargetLowering][ExpandABD] Prefer selects over usubo if we do the same for ucmp (#159889) Same deal we use for determining ucmp vs scmp. Using selects on platforms that like selects is better than using usubo. Rename function to be more general fitting this new description.
