MakeCallsStatic (GWT 2.7.0)

```
public class MakeCallsStatic
extends Object
```
This is an interesting "optimization". It's not really an optimization in and of itself, but it opens the door to other optimizations. The basic idea is that you look for calls to instance methods that are not actually polymorphic. In other words, the target method is (effectively) final, not overridden anywhere in the compilation. We rewrite the single instance method as a static method that contains the implementation plus an instance method that delegates to the static method. Then we update any call sites to call the static method instead. This opens the door to further optimizations, reduces use of the long "this" keyword in the resulting JavaScript, and in most cases the polymorphic version can be pruned later.
