debugment of our nasty codegen issues.  :)

  1. Each time the loop extractor extracted a loop, we would leak a module.
  2. When we extracted a loop, we didn't add the new function to the list of
     miscompiled functions.  Thus if the bug was in a loop nest and we
     extracted it, we could actually *LOSE THE BUG*, which is very bad.

With these patches, bugpoint has successfully found a bug for me in a function
with several nested loops, and cut it down to just one of them. :) :)

miscompiled, try to use the loop extractor to reduce the program down to a
loop nest that is being miscompiled.  In practice, the loop extractor appears
to have too many bugs for this to be useful, but hopefully they will be fixed
soon...

 * Make several methods of bugdriver global functions (ParseInputFile, PrintFunctionList)
 * Make PrintFunctionList truncate the output after 10 entries, like the crash debugger
   did.  This allows code sharing.
 * Add a couple of methods to BugDriver that allows us to eliminate some friends
 * Improve comments in ExtractFunction.cpp
 * Make classes that used to be friends up bugdriver now live in anon namespaces
 * Rip a bunch of functionality in the miscompilation tester into a new
   TestMergedProgram function for future code sharing.
 * Fix a bug in the miscompilation tester induced in my last checkin
