The current emscripten EH is enabled by `-mllvm -enable-emscripten-cxx-exceptions`, which is not a clang flag (it's passed by `-mllvm`). The reason it is not a clang flag is emscripten EH does not need any action in clang. If users use exceptions but don't pass `-fwasm-exceptions`, if they pass `-mllvm -enable-emscripten-cxx-exceptions` instead, emscripten EH will be used. If they pass neither, neither EH will be used and all invokes will be lowered to calls. Having said that, `-fwasm-exceptions` and `-mllvm -enable-emscripten-cxx-exceptions` are not compatible. If we can check this that'd be better. I'll check.
