If a class's version V is in this range:

STACKMAP_ATTRIBUTE_MAJOR_VERSION <= V < NOFAILOVER_MAJOR_VERSION

It can fail the new verifier but can succeed with the old verifier. This is called "fail over verification".

Currently these classes are excluded from the AOT cache:

After JDK-8317269, we are able be able to store classes verified by the old verifier. Therefore, we should modify the above code to support classes verified with "fail over" verification.
