SSE1 has an explicit SIMD fence operation that guarantees synchronization between threads. Currently this is not observable in JS and so for all purposes, this can be a no-op, but in the future with the SharedArrayBuffer work, this will be observable. Marking down this issue to discuss if we can support this at some point?

SSE1 and SSE2 fences have been implemented as full barriers.
