      In the process of testing JDK-8354282, we noticed that BoolNode::Value_cmpu_and_mask() does not look through cast nodes. Even though it is quite an edge case, we should update BoolNode::Value_cmpu_and_mask() to look through cast nodes.

      We split this to a separate RFE since we are currently already in RDP 1 for JDK 26 and JDK-8354282 needs to be backported.

      I attached an IR test that works before JDK-8354282 but fails afterwards. No additional flags required.
