Frits van Bommel 9bbe849fc3 Fix a bug in the loop in JumpThreading::ProcessThreadableEdges() where it could falsely produce a MultipleDestSentinel value if the first predecessor ended with an 'indirectbr'. If that happened, it caused an unnecessary FindMostPopularDest() call. ...

This wasn't a correctness problem, but it broke the fast path for single-predecessor blocks.
