I wonder if we could get away with making the Atomics methods not coerce. Surely no one is doing that? Emscripten isn't at any rate (except possibly undefined, which is a little harder to tell) and it's the primary consumer afaik. And it's definitely a place I'd expect to find engine/spec bugs (e.g. https://github.com/tc39/ecma262/pull/3926)
