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
