      Description

      If you run current test on 11u AArch64, then Shenandoah would fail:

      $ CONF=linux-aarch64-normal-server-fastdebug make run-test TEST=compiler/c2/aarch64/TestVolatilesShenandoah.java

      TEST RESULT: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: Missing expected output cmpxchgw?_acq_shenandoah!

      This is because the 11.0.9 backport brought the test in broken form.

      Compare for example:
