It's quite orthogonal to that. We just need to make sure that we use
the new FIAT interface in stage 2.

Note that with this new design (which is really just a stricter
and cleaner version of what I originally intended) FIAT will only be
called in stage 2 which will make things easier.

I will start on changing things from the top and down, starting with
cleanups in compiler.py and then we can go from there.
