* 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

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).

Speed up convergence significantly and also reduce the size of testcases by making large portions of a function's CFG dead at a time.
