Sun Jan 12 13:48:03 UTC 2025

Hi,

While working on [JDK-8347365](https://bugs.openjdk.org/browse/JDK-8347365), I noticed that there are some nodes that have their control inputs being set in a seemingly erroneous manner. This patch removes the control inputs for those nodes.

Please review this PR, thanks a lot.
