[PATCH] [NFC] Make the maximal loop depth an absolut value.

[Tobias Grosser]

Hi Johannes,

the patch looks generally reasonable, even though it does not explain why the additional information is necessary. As the patch is rather simple, it should be OK to commit it in case you have a use case for it.

----------------
Why do we need to add one only in case MinLoopDepth > 0? This may be worth a comment.
