903a90b9de Disambiguate symbols after loop extraction so that we can diagnose a code 
generator bug if multiple loops are extracted from a function.

d2c51f2cc3 Merge the code generator miscompilation code into the optimizer miscompilation 
code.  This "instantly" gives us loop-extractor power to assist with the
debugment of our nasty codegen issues.  :)

950f3fac90 Fix two pretty serious bugs: 
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. :) :)

4ef444f59b After reducing a miscompiled program down to the functions which are being 
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...

491f3054b8 Refactor and clean up a bunch more code. No major functionality changes. 
* 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

dc004a7269 We have this snazzy link-time optimizer. How about we start using it? This 
removes some cruft from 255.vortex, cleaning up after DAE and IPCP, which
do horrible, beautiful, things to vortex.
