RFR: 8352418: Add verification code to check that the associated loop nodes of useless Template Assertion Predicates are dead [v2]

[Christian Hagedorn]

> As already suggested in https://github.com/openjdk/jdk/pull/23823, I want to do the following additional verification:
> 
> After `eliminate_useless_predicates()` all now useless `OpaqueTemplateAssertionPredicate` nodes should not have any references to `CountedLoop` nodes that are still in the graph (otherwise, they would have been marked useful). This verification did not work reliably without the full Assertion Predicates fix [JDK-8350577](https://bugs.openjdk.org/browse/JDK-8350577). Since JDK-8350577 is now integrated, I propose to add this additional verification code.
