This should improve performance of these members in most cases:
- toString
- operator ==
- hashCode
- runtimeType
- noSuchMethod
The helpers for checking `null` and then dispatching to the method are now very small again. Also, because we can lookup symbolized names always, we can start taking advantage of this in our Map/Set implementations (for a follow up CL).
This also improves correctness of these helpers given JavaScript objects; we were previously falling back to calling a Dart method name like `.hashCode`, which is incorrect (except for `toString` where fallback is probably the correct behavior).
