a1cf1c8c87 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...

efdc0b5057 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

be21ca54e0 Refactor all of the "splitting a module into two pieces" code to avoid 
code duplication.  Also, don't use ReduceMiscompilingFunctions::TestFuncs
to print out the final message.

fcb6ec0c7e I hate it when bugpoint is all ready to give me a bytecode file, then crashes 
in final cleanups.  Then you had to run the whole mess again with
-disable-final-cleanups.

This makes bugpoint run the cleanups in a protected environment so that if
they crash, bugpoint itself doesn't crash.  This makes things much happier,
implements a FIXME, and gets rid of YABPO (yet another bugpoint option).

ba386d943f * Reduce the number of useless bytecode files produced by bugpoint. 
- This also speeds it up as the bytecode writer isn't terribly fast.
* Add a new cleanup pass after everything else to run -funcresolve -globaldce
