[Haskell-cafe] External Core

I am still working on it. Some external events have slowed me down a  
little (research, classes, appendicitis), and it has involved more  
changes to the innards of GHC than anticipated, but it is still  
moving along. If you can wait a little while, it should be possible  
to use GHC.

A slight extension of what I'm doing, which would probably be very  
useful, would be to export functions for working with external core  
from the GHC API.
