Explicitly opt-in to READ_ONCE/WRITE_ONCE semantics
We mark all atomic variables as volatile and have our atomic accessors
built around that. We probably, therefore, want Linux-style
READ/WRITE_ONCE semantics of implying memory barriers. /volatile:ms does
this automatically.
This was already the default on amd64 and x86 but not on ARM.
