> This is a workaround for the fact that %SetCode can "lose" the script for a js native. If the js native is re-initialized (for a Realm or something), then the source SharedFunctionInfo won't have a script anymore. Nonetheless, we may want to optimize the function. If we've compiled bytecode, then we can compile optimized code without a script.
