Yes, it should be `vm.flagless`, since it runs in driver mode with `executeLimitedTestJava`. But it should also remain `vm.debug & vm.bits == "64"`, because `CountBytecodes` option is `develop` (so it is not available in release builds), and the counter would likely overflow in 32-bit modes ([JDK-8350642](https://bugs.openjdk.org/browse/JDK-8350642) made the counter 64-bit only for 64-bit platforms).

So just add `@requires vm.flagless`, leaving the other `@requires` alone.

Run the test with both fastdebug and release builds to confirm it still works.
