String.compareTo intrinsic for AArch64

[Yudi Zheng]

Hi Dmitry,

Thanks for the contribution (again)!

Recently we discover that the AMD64 String.compareTo intrinsic on Java 8
might occasionally lead to HotSpot crashes. I have create a pull request
https://github.com/oracle/graal/pull/315 <https://github.com/oracle/graal/pull/315>, and hopefully that would address
the issue. Since I cannot assign you as the reviewer, could you please
leave a comment there whether it is good to go? Once that gets in, the
test cases will be enabled again.

GR-8748 is from our internal JIRA tracker.

Thanks,
Yudi
