Original bug:
https://bugs.openjdk.java.net/browse/JDK-8223177
https://hg.openjdk.java.net/jdk/jdk/rev/27c8a2e0b0e5
This patch applies to 8u, but does not compile, because regular OrderAccess methods do not accept
pointers. We need to use the *_ptr_* versions of the same methods and do casts from void*.

Testing: tier1
