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. :) :)

Implement a small optimization. In test/Regression/CodeGen/X86/select.ll,
we now generate this for foldSel3:
foldSel3:
mov %AL, BYTE PTR [%ESP + 4]
fld DWORD PTR [%ESP + 8]
fld DWORD PTR [%ESP + 12]
mov %EAX, DWORD PTR [%ESP + 16]
mov %ECX, DWORD PTR [%ESP + 20]
cmp %EAX, %ECX
fxch %ST(1)
fcmovae %ST(0), %ST(1)
*** fstp %ST(1)
ret
Instead of:
foldSel3:
mov %AL, BYTE PTR [%ESP + 4]
fld DWORD PTR [%ESP + 8]
fld DWORD PTR [%ESP + 12]
mov %EAX, DWORD PTR [%ESP + 16]
mov %ECX, DWORD PTR [%ESP + 20]
cmp %EAX, %ECX
fxch %ST(1)
fcmovae %ST(0), %ST(1)
*** fxch %ST(1)
*** fstp %ST(0)
ret
In practice, this only effects code size: performance should be basically
unaffected.
