Sanjoy Das 5e3a215bf7 [SCEV] See through op.with.overflow intrinsics (re-apply) ... Summary: This change teaches SCEV to see reduce `(extractvalue 0 (op.with.overflow X Y))` into `op X Y` (with a no-wrap tag if possible). This was first checked in at r265912 but reverted in r265950 because it exposed some issues around how SCEV handled post-inc add recurrences. Those issues have now been fixed.
