Please review the following webrev


JIRA issue: https://bugs.openjdk.java.net/browse/JDK-8135231

This adds support for vector double sqrt for aarch64.

I have tested this with JTreg hotspot+langtools with no regressions.

There is a trivial change to

-* @requires os.arch=="x86" | os.arch=="amd64" | os.arch=="x86_64"
+* @requires os.arch=="x86" | os.arch=="amd64" | os.arch=="x86_64" |

I am not clear whether this change means that the change requires
sponsoring and pushing through JPRT, but if so could someone do this.

Thanks for your help,
