<!-- Thank you for contributing to Ruff! To help us out with reviewing, please consider the following: - Does this pull request include a summary of the change? (See below.) - Does this pull request include a descriptive title? - Does this pull request include references to any relevant issues? --> ## Summary Introduces the skeleton of the flow graph. So far it doesn't actually handle any non-linear control flow :) But it does show how we can go from an expression that references a symbol, backward through the flow graph, to find reachable definitions of that symbol. Adding non-linear control flow will mean adding flow nodes with multiple predecessors, which will introduce more complexity into `ReachableDefinitionsIterator.next()`. But one step at a time. ## Test Plan Added a (very basic) test. |
