* Do not refer to ActualCallees in CBU, when we can do it locally.

* *DO NOT* print CBU graphs when asked to print our own.  This is just
  FREAKING confusing and misleading: it's better to not print anything.
* Simplify and clean up some code
* Add some more paranoia assertion checking code that I found to track
  down this bug:
* Fix a nasty bug that was causing us to crash on Prolangs-C++/objects,
  where we were missing processing some graphs.  This hunk is the bugfix:

-    if (!I->isExternal() && !FoldedGraphsMap.count(I))
+    if (!I->isExternal() && !ValMap.count(I))

  urg!
