WIP

- [ ] if we do this it needs to be a build step (so firefox OS certified and PS3 certified apps can use it)
- [ ] make it work with super in mixins
- [ ] ember-cli mixin 

Specific improvements doesn't really seem like much as we have already reduced superWrapper. But in terms of reducing overall cost of super, it is a really nice step. As this doesn't require a rebind, nor a super wrapper. 

This should allow and enable further runtime optimizations as well as fix some existing super issues.

For example, if an error is thrown __nextSuper may not be restored correctly.

This may still have other implications I have not thought about yet.
