[aarch64-port-dev ] RFR: Backports from jdk9 to jdk8

[Edward Nevill]

Hi,

The following webrev backports a number of changesets from jdk9 to jdk8.

http://cr.openjdk.java.net/~enevill/jdk8-backports/

The changesets are backported are listed below.

Where possible I have kept the changeset unchanged by export from jdk9 and import direct into jdk8.

In the case of some changesets this was not possible because of conflicts. In these cases I have applied the changes manually. However in all cases I have attributed the author of the changeset correctly.

I have tested with jtreg hotspot with the following results:-

Original: Test results: passed: 650; failed: 19
Patched: Test results: passed: 650; failed: 19

OK to push to jdk8?

Ed.
