Instead of chasing exports in each FileState library individually, we perform recursive computation, and remember computed export namespaces for visited branches. Cycles require special handling - we don't remember partial namespaces, we compute one full export namespace and so break the cycle; then the rest also can be computed in one pass. This makes Analysis Server a bit faster for some Quick Fixes, and what is more important, is a playground to test the idea of makeing the similar change to _Prelinker. We spend 8% of total analysis time chasing long chains of exports in Flutter.
