@TobiHartmann and I just had a chat and he is right. If the changes in `PhaseIterGVN::verify_Identity_for` are applied, we will hit [JDK-8374896](https://bugs.openjdk.org/browse/JDK-8374896). So, I will revert that part of the change. Note that the IR test does not rely on `VerifyIterativeGVN` being enabled.
