[aarch64-port-dev ] RFR: Backports to jdk8

[Edward Nevill]

Hi,

I would like to backport the patches changesets below from jdk9 to jdk8.

I have tested server and client builds and also a server slowdebug build.

The following are the jtreg results for hotspot and langtools from the server-release build (results before and after were identical).

Hotspot: Test results: passed: 675; failed: 17; error: 3
Langtools: Test results: passed: 3,091

OK to push?

Ed.
