IControlFlowGraph was modeled after the Roslyn CFG API, where a block can have at most two successors - a fall-through successor, and a conditional successor. Switch statements are represented as a chain of checks for one case at a time.
This doesn't generalize well to CFGs in IL which can have more than two branch targets for a switch instruction. This changes the interface to expose an IEnumerable of successors.
