Having a LLVM backend would not only benefit HedgeWar's JavaScript case, 
but also all others that would like to use the LLVM backend for one 
purpose or the other. And in my opinion a pure JS backend would be much 
harder to implement than a LLVM backend as one also needs to think about 
how certain things should be implemented in JS (which the emscripten 
developers already thought of).
