Post-dominator data.

This is surely a simple question, but it appears that PostDominatorTree does not provide an interface to get at post dominator data. Also, it is not a concrete subclass of DominatorTree, as is presented in the doxygen page and the commented source. Any way to get post-dom data without hacking it into PostDominatorTree?

Is our post-dom pass solid? I thought it's fair expensive so we avoid using it.

Our "post-dom pass" is just the dom pass with a boolean set the other
way. I don't see how it could be significantly more expensive. I
don't think any in-tree passes use it, though.
