Refactor scatter/gather tests to be included in the load/store test classes and
expand to support access between `ShortVector` and and `char[]`, and access
between `ByteVector` and `boolean[]`.
Vector tests pass on linux-x64 linux-aarch64 macosx-x64, and windows-x64.

Test that when the jdk.incubator.vector module is present that libsvml.so is
present, and test the opposite case.

Thumbs up!
Thanks for doing this sync forward.

Marked as reviewed by dcubed (Reviewer).

This patch contains another minor tweak to TestResourceScope as we have seen
this test timing out at least once (on arm64).
I realized that some of the logic recently introduced in the test could lead to
the test waiting forever: for instance, if all threads are executed right away
before the m

Hi,
we observe crashes in jdk 11.0.12 on Windows:
https://bugs.openjdk.java.net/browse/JDK-8267440
I haven’t found any backport which looks like obviously causing it.
We had different theories which include:
* Antivirus tool which keeps the test file open.
* Error in handling of OVERLAP
