JDK-8293117 added a suite of atomic operations for manipulating integer values representing bitsets. The default implementation provided there uses a loop over Atomic::cmpxchg. It also provided a mechanism for specializing the implementation by platform-specific code. We should provide such a specialization for the platform named in the summary, if that's possible. (If there isn't a better implementation then this issue can just be closed.)
