In rG6a076fa9539e, a problem with updating the old/narrow phi nodes after IV widening was introduced. If after widening of the IV the transformation is *not* applied, the narrow phi node was incorrectly modified, which should only happen if flattening happens. This can be seen in the added test widen-iv2.ll, which incorrectly had 1 incoming value, but should have its original 2 incoming values, which is now restored.
