nit: Is this comment still correct?

The model comment hasn't been right for a while (it's owned by
AppListServiceSyncable in Chrome builds), but it's out of place here anyway.
Here, I've put

    // Note the AppListViewDelegate outlives the AppListView. For Ash, the view
    // is destroyed when dismissed.

     // will be released with AppListView on close.
     app_list::AppListView* view = new app_list::AppListView(
-        Shell::GetInstance()->delegate()->CreateAppListViewDelegate());
+        Shell::GetInstance()->delegate()->GetAppListViewDelegate());
     aura::Window* root_window = window->GetRootWindow();
     aura::Window* container = GetRootWindowController(root_window)->
         GetContainer(kShellWindowId_AppListContainer);
