[PATCH] D37265: [SCEV] Ensure ScalarEvolution::createAddRecFromPHIWithCastsImpl properly handles out of range truncations of the start and accum values

Note: I'm not sure how resource management works in SCEV. There are some SCEVs being created here before the bail-out (return None) that are not explicitly deleted. Do we need to delete these, or is there some sort of SCEV resource management thing going on under the hood?
