CodeExtractor looks up the dominator node corresponding to return blocks when splitting them. If one of these blocks is unreachable, there's no node in the Dom and CodeExtractor crashes because it doesn't check for domtree node validity. In theory, we could add just a check for skipping null DTNodes in `splitReturnBlock` but the fix I propose here is slightly different. To the best of my knowledge, unreachable blocks are irrelevant for the algorithm, therefore we can just skip them when building the candidate set in the constructor.
