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...
