This is an umbrella issue for new tests that might be needed for compiler replay. For example:
1. tests for VM anonymous classes invoked through constant pool (invokedynamic) [mostly done]
2. tests for VM anonymous classes invoked through MethodHandle
3. tests for dynamically-genereated classes (requires serialization of data for proper replay) [not currently on radar]
4. tests for existing replay failures (see ci-replay-failed tag)
5. tests for unresolved replay bugs/RFEs
