This revision is now accepted and ready to land.

If a cross-platform version of this function emerges, we can always update the name here and in emscripten later. I think this is fine to merge now because it is consistent in the context of things that exist today and can easily be extended. I also think it is good to leave this as a compiler error; there's not much of a difference between this and any other runtime function that wasm does not support but that an individual user might want to supply. Maybe a separate PR should make all runtime functions linker errors instead of compile errors?
