I'm adjusting this test to require `vm.bits` is 64 as per similar [tests](https://github.com/openjdk/jdk/blob/85715e1050fa774c3267dbbe2f749717aeeec8ff/test/hotspot/jtreg/runtime/CompressedOops/CompressedKlassPointerAndOops.java#L31).

@Hamlin-Li : same as the other PR, please respect the 24h rule when sponsoring. The author did not even suggest that it is trivial. Thanks.
