Chris Lattner 5e783ab0b5 Implement basic block extraction for the miscompilation debugger. This still needs
two things: the FIXME in ExtractBlocks needs to be implemented, and the basic block
extractor itself needs to have enough bugs fixed for this to be more or less
useful.

Until the time that this is generally useful, it is hidden behind the new bugpoint
-enable-block-extraction option.  I hope to get the FIXME done tonight.

Also of note, this patch adds a -extract-bbs option to bugpoint which can be used
to debug the block extractor.  (hint hint Misha :)

Chris Lattner 87ab7e994f Fix a fairly nasty bug that prevented bugpoint from working quite right when
hacking on programs with two functions that have the same name.

Chris Lattner 7fa44fca30 Fix an inverted condition that causes us to think that loop extraction
accomplished something when it really did not.  This does not fix the bigger problem tho.

Chris Lattner 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...

Chris Lattner 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

code duplication.  Also, don't use ReduceMiscompilingFunctions::TestFuncs
to print out the final message.

Chris Lattner 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).
