RFR: 8350563: C2 compilation fails because PhaseCCP does not reach a fixpoint [v3]

[Liam Miller-Cushon]

> Hello, please consider this fix for [JDK-8350563](https://bugs.openjdk.org/browse/JDK-8350563) contributed by my colleague Matthias Ernst.
> 
> https://github.com/openjdk/jdk/pull/22856 introduced a new `Value()` optimization for the pattern `AndIL(Con, Mask)`.
> This optimization can look through CastNodes, and therefore requires additional logic in CCP to push these
> transitive uses to the worklist.
> 
> The optimization is closely related to analogous optimizations for SHIFT nodes, and we also extend the existing logic for
> CCP worklist handling: the current logic is "if the shift input to a SHIFT node changes, push indirect AND node uses to the CCP worklist".
> We extend it by adding "if the (new) type of a node is an IntegerType that `is_con, ...` to the predicate.
