Florian Hahn b93c06331e [CodeExtractor] Fix iterator invalidation in findOrCreateBlockForHoisting. 
Summary:
By replacing branches to CommonExitBlock, we remove the node from
CommonExitBlock's predecessors, invalidating the iterator. The problem
is exposed when the common exit block has multiple predecessors and
needs to sink lifetime info. The modification in the test case trigger
the issue.
