RFR: Backports to aarch64 jdk7

[Edward Nevill]

Hi,

Please review the following webrev

http://cr.openjdk.java.net/~enevill/jdk7_backports_1605/webrev

This backports the changes listed below to jdk7.

I have only backported bug fixes as I think it is no longer appropriate
to backport optimisations to jdk7.

Tested with hotspot and langtools

Before:

Hotspot: Test results: passed: 297; failed: 12; error: 2
Langtools: Test results: passed: 1,970; failed: 1; error: 2

After:

Hotspot: Test results: passed: 297; failed: 12; error: 2
Langtools: Test results: passed: 1,972; failed: 1; error: 1

OK to push?

Ed.
