Correctly transforming the bonsai (ping @cvogt)
First stab at duplicator - specialzier separation

```
             extmethods   7  add extension methods for inline classes
               hijacker   8
                pickler   9  serialize symbol tables
              refchecks  10  reference/override checking, translate nested objects
           selectiveanf  11
           selectivecps  12
                uncurry  13  uncurry, translate function values to anonymous classes
           minibox-dupl  14
           minibox-spec  15
              tailcalls  16  replace tail calls by jumps
             specialize  17  @specialized-driven class and method specialization
```
Specialization hijacker, minibox-dupl and minibox-spec are now added :)

Checkpoint, problems with forwarders
Forwarding relies on rewiring

Instead of computing all the conversions and tags upfront. There are
many todos in the area of checking the rewiring will be correct, but
luckily we have tests for that.
