GHCi does indeed generate byte code, but we have never gotten around to
trying to dump it into files and reload it. That might be an
interesting project -- but it only gives a constant performance factor
over loading the source files in the first place, so it's not clear that
it's a major win.
The major win with having the byte code in a file is that you could
have a stand alone byte code interpreter (and runtime system).
That would make bootstrapping GHC a much less daunting task.
