Florian Hahn f0a25f7253 [CloneFunction] Support BB == PredBB in DuplicateInstructionsInSplit. ...

In case PredBB == BB and StopAt == BB's terminator, StopAt != &*BI will
fail, because BB's terminator instruction gets replaced.

By using BB.getTerminator() we get the current terminator which we can use
to compare.
