[aarch64-port-dev ] aarch64: C2 fast lock/unlock issues

[Andrew Dinn]

Thank you for proposing these fixes. Your analysis and patch both look
to me to be completely correct. I applied the patch and it appears to
work fine when running programs with biased locking enabled.

I have raised the following JIRA for this fix:

  https://bugs.openjdk.java.net/browse/JDK-8134322

I will post a webrev containing your patch for review as soon as possible.

regards,


Andrew Dinn
