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...

 * 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

Add ProgramExitedNonzero argument to executeProgram(), and make it
tell its caller whether the program exited nonzero.

Move executeProgramWithCBE() out of line, to ExecutionDriver.cpp, and remove
its extra arguments which are always defaulted.  Make it turn off
check-exit-code if the program exits nonzero while generating a reference
output.

Make diffProgram() assume that any nonzero exit code is a failure, if
check-exit-code is turned on.
