Regular C++ exceptions are deactivated when compiled with 'emcc' since adding
them (using Emscripten runtime mechanism) practically doubles the size of the generated wasm library.
A 'light' exception handling model is used:
- C++ 'throw' is actually catched by the Emscripten runtime 'catch_throw' and the exception
error message is kept in the global faustexception::gJSExceptionMsg variable
- a regular JS exception is triggered and catched on JS side
- the actual exception message is retrieved on JS side using 'getErrorAfterException'
- and finally global context cleanup is done from JS side using 'cleanupAfterException'
