I would like to fork the new tests off the JDK-8150730, to get the broader coverage for the current arraycopy stubs, and stabilize the tests before doing any stub improvements integration. Plus, it gives us the ability to backport the tests cleanly.

Fix Request (11u) Improves arraycopy stubs testing. Applies semi-cleanly, requires a bit of fiddling with test group definitions. Passes new tests on x86_64, x86_32, AArch64.
