Clean backport of [JDK-8307572](https://bugs.openjdk.org/browse/JDK-8307572) to fix a hidden aarch64 issue, which may cause incorrect result with several common intrinsics used. Test case included in the patch failed without the fix and passed with this patch. No new jtreg test failure with both release and fastdebug build.
