I am only snarly about this because i do not want to give up marking
recurrences as pure or const. That will, in the long run, cost us.
Mark and i talked about adding another bit to the tree so that we could
support non recursive and recursive pure and const functions. the
recursive ones could still be cse'd but not dce'd. This is not
appropriate for stage 3.
