cmd/go: search breadth-first instead of depth-first for test dependency cycles When we are looking for a dependency cycle involving a specific package, we need to keep track of visited packages in order to avoid repeatedly traversing a cycle that does not involve that package. If we're keeping track of all visited packages anyway, we're already spending O(N) memory on the traversal, so we may as well use breadth-first search. That not only keeps the bookkeeping simple, but also guarantees that we will find a shortest path (rather than a completely arbitrary one).
