Remove all optimized code whenever we load scripts/libraries/snapshots. Currently this occurs only when no Dart frame is live on stack. Future change (deoptimization) will allow dynamic class loading in presence of live Dart frames. The cost of removing all optimized code is supposed to be low. If that assumptions turns out to be false I can add more elaborate tracking of optimized functions.
