[aarch64-port-dev ] JDK9: Merge in recent changes from JDK8 tree

[Edward Nevill]

Hi,

The following changesets merge the JDK9 hotspot tree to the same state as the JDK8 tip.

I have tested the resultant tree with jtreg hotspot and langtools.

None of the changesets involve changes to shared code.

Regards,
Ed.
