a1346a2619 Disable strict alias analysis in the backend c compiler, as the code we
generate is not TBAA safe.

121f09fb05 Right, we break strict aliasing requirements. Make sure to disable strict
aliasing in the C compiler.

a57d86b436 Merge the code generator miscompilation code into the optimizer miscompilation
code.  This "instantly" gives us loop-extractor power to assist with the
debugment of our nasty codegen issues.  :)

5313f23b8c Fix two pretty serious bugs:
1. Each time the loop extractor extracted a loop, we would leak a module.
  2. When we extracted a loop, we didn't add the new function to the list of
     miscompiled functions.  Thus if the bug was in a loop nest and we
     extracted it, we could actually *LOSE THE BUG*, which is very bad.

With these patches, bugpoint has successfully found a bug for me in a function
with several nested loops, and cut it down to just one of them. :) :)

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...

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
