Thanks, going to push it soon.

Maybe? I don't see any code for JDK-8223511 yet, so cannot really judge. If it backported quite a
bit already, we can indeed consider backporting the rest. On the other hand, that diagnostics is
mostly useful when adding/modifying JDK-JVM intrinsics list, which is rare (and certainly very rare
for backports). I can tell when all the bits and pieces are in public repo.
