hacking on programs with two functions that have the same name.

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...

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

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).
