Can we move this into Factory::NewSharedFunctionInfo (the one that takes a code
object)? I think that is a more general chocking point for allocation. Also I
would like to keep this a pure copying function without any logic in it. I am
fine with passing the is_generator flag as a simple boolean flag to
NewSharedFunctionInfo for now.

Done.

+    String *class_name = function_info->GetHeap()->Generator_string();
+    function_info->set_instance_class_name(class_name);
+  }
 }
