4ef444f59b 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...

491f3054b8 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

36e8168af5 Refactor all of the "splitting a module into two pieces" code to avoid 
code duplication.  Also, don't use ReduceMiscompilingFunctions::TestFuncs
to print out the final message.

228bd4e931 Turn on argument promotion in gccas. This can give us substantially better 
code in cases where the file has lots of static functions or anon namespaces.

dc004a7269 We have this snazzy link-time optimizer. How about we start using it? This 
removes some cruft from 255.vortex, cleaning up after DAE and IPCP, which
do horrible, beautiful, things to vortex.
