Copperbox revision 3179.

I've finally worked on the super-call inlining code. At the moment it doesn't quite work as there are a couple of standout bugs, fixing them suggests some rethinking, so I'm committing the "code so far".

I also have a more over-arching worry that super-inlining and inheritance flattening should be done at the same time, but investigating this will have to wait.
