too!

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. :)

  - make sure to check the indvar type before anything else (efficiency)
  - Make sure to insert the 'add' into the program, even though it'll be
    dead
  - Wrap code at 80 columns
  - Other minor cleanups to reduce indentation level

  * Increases consistency with other iterators (e.g. df_iterator, po_iterator...)
  * It's shorter
  * We don't name classes by the implementation, we name it for the interface!

another delayed instr. would cause the later sanity-check (assertion)
in PhyRegAlloc.cpp to fail, even though there is really no error.
