David Blaikie 017ba3988f CFG::SuccessorIterator: Remove explicit copy assignment, as the default is fine
There's no reason to disallow assigning an iterator from one range to an
iterator that previously iterated over a disjoint range. This then
follows the Rule of Zero, allowing implicit copy construction to be used
without hitting the case that's deprecated in C++11.
