I already was working on this some months ago, but at the time Diego
felt it would probably not be worth doing on trees, so I never finished
it.  Here's that file, perhaps there's something in it you can still
use.

What I was working on was supposed to run on the CFG in SSA form so that
it can run after the must-alias pass.
