I think this should always be used since we are part of resolution here. The
else branch might be from when constructors didn't have their simple names.

     } else {
-      element = classElement.lookupConstructor(
-          new Selector.callDefaultConstructor(classElement.library));
+      element = classElement.lookupDefaultConstructor();
