Where will this show up? All actual JsvaScript functions will now get the
constructor name "(closure)".

'constructor_name' is only used in heap profiler. Factories use 'class_name'
function declared above.

   }
   if (map()->constructor()->IsJSFunction()) {
     JSFunction* constructor = JSFunction::cast(map()->constructor());
