Hmm, I don't understand this.  Why is it harder to find a sweet spot
if every pass decides for itself whether to run or not?  I would think
that this decision should be made by each pass individually, because
the pass manager is one abstraction level higher where it shouldn't
have to know the behavior of each pass.
