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. :) :)
