ART: Do not eagerly type LoopPhi [null, ...] ReferenceTypePropagation would eagerly set the type of each loop phi to the type of the first input prior to beginning the fix-point iteration. While this does make the algorithm converge faster, it should not be applied when the first input is a NullConstant becuase that sets the type of the phi and all dependent instructions to Object.
