Sadly, it was all written to be of use to people who wanted to write
sane, rather than completely ad-hoc, dataflow optimizers for our
backend.  This just didn't happen, for a variety of reasons.
:)

A lot of the functions were there so that people wouldn't do it for lack
of support functions that did what they want.

The only one i really object to  changing is iterative_dataflow.

There are a lot of things that *should* be using it, and i intend to
change them to use it sometime in the 4.1 lifetime.
It was always intended to be an external interface.
