[jdk19u] RFR: 8287217: C2: PhaseCCP: remove not visited nodes, prevent type inconsistency

Tue Nov 22 16:20:07 UTC 2022

Backport of [JDK-8287217](https://bugs.openjdk.java.net/browse/JDK-8287217). Patch did not apply cleanly due to differences in surrounding code in `PhaseCCP::analyze`. Approval is pending.

Thanks,
Tobias
