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

[Edward Nevill]

Hi,

http://cr.openjdk.java.net/~enevill/jdk8_backports/

backports the changesets below to jdk8.

Tested with jtreg hotspot/langtools/jdk

Before:

Hotspot: Test results: passed: 672; failed: 19; error: 2
Langtools: Test results: passed: 3,090
JDK: Test results: passed: 5,526; failed: 224; error: 11

After:

Hotspot: Test results: passed: 672; failed: 19; error: 2
Langtools: Test results: passed: 3,091
JDK: Test results: passed: 5,520; failed: 224; error: 16

I have also build and smoke tested a cross section of builds

- cross compile
- builtin sim
- native compilation
- zero, client, server
- release/fastdebug/slowdebug

OK to push?
Ed.
