Description
8u fails without JDK-8134739 fix. Unfortunately, it does not reproduce on compiler/loopopts/superword/TestVectorizationWithInvariant from there. It does, however, reproduce on fuzzer tests that we luckily got (attached as 0021.tar.gz in JDK-8134739). We should really turn that into proper additional regression test for JDK-8134739.

This would allow us to test 8u backports better.
Comments
Fix Request (13u) This test provides safety net for compiler work, and keeps test base the same across releases. Patch applies cleanly to 13u and new test passes.

Fix Request (8u) This test provides safety net for compiler work, and keeps test base the same across releases. It serves as regression test for JDK-8010500, to be pushed before this changeset. Patch applies to 8u with reshuffling and new test passes.

Fix Request (11u) This test provides safety net for compiler work, and keeps test base the same across releases. This backport is the intermediary stop towards backporting to 8u. Patch applies cleanly to 11u and new test passes.
