> Backporting JDK-8321204: C2: assert(false) failed: node should be in igvn hash table. Adjusts assert added by [JDK-8024070](https://bugs.openjdk.org/browse/JDK-8024070) and adds additional condition that `Node::hash` is non zero. Ran GHA Sanity Checks, local Tier 1 and 2 tests. Patch is not clean due to skipping the [JDK-8312218](https://bugs.openjdk.org/browse/JDK-8312218) (which is reverted by this commit anyway).
