Yeah there are tons of places that CPU performance matters, but my point is that Mozilla and WebKit's engines are doing a good job of native compilation already.
If you could make a CoffeeScript compiler that would output asm.js, then great. But I'm not sure that's possible. I think that you either have to go from C/C++ code through the emscripten or right directly using the asm.js stuff in JavaScript.
