Can we at least have a runtime assert that checks that call_site is either
javascript or wasm? This has been put here to check that the CallSite object has
been successfully constructed. I.e. the argument call_site_obj indeed has the
correct properties.

Done.

     return RETURN(call_site.NAME(), isolate);               \
   }
