Sanjoy Das 79b9222927 Teach SCEV normalization to de/normalize non-affine add recs ... Summary: Before this change, SCEV Normalization would incorrectly normalize non-affine add recurrences. To work around this there was (still is) a check in place to make sure we only tried to normalize affine add recurrences. We recently found a bug in aforementioned check to bail out of normalizing non-affine add recurrences. However, instead of fixing the bailout, I have decided to teach SCEV normalization to work correctly with non-affine add recurrences, making the bailout unnecessary (I'll remove it in a subsequent change). I've also added some unit tests (which would have failed before this change).
