b7c4c992be This is a disgusting hack that improves code substantially, by making
callgraphSCC passes more effective.

50b5d71cb7 Make use of "external" depth-first iterators to avoid revisiting nodes
multiple times.  This reduces the time to construct post-dominance sets a LOT.
For example, optimizing perlbmk goes from taking 12.9894s to 1.4074s.

706e61ead9 Rework post dominator information so that we do not have to
unify all exit nodes of a function to compute post-dominance information.
This does not work with functions that have both unwind and return nodes,
because we cannot unify these blocks.  The new implementation is better
anyway. :)
