Instead, check all uses.
This fixes bug: ScalarRepl/2003-09-12-IncorrectPromote.ll
This also fixes the miscompilation of Ptrdist/bc

  - Only rerun passes if the previous thing changed something

construction.  Now there may be multiple root blocks, and null is a
special node used to mark the "virtual" exit node of a CFG.

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
