... which will update both the CodeObjectSlot contents and the cached value of the code entry point when the pointed Code object is evacuated. This is done by introducing an OLD_TO_CODE remembered set which is populated with the recorded slots containing pointers to Code objects. CodeDataContainer is the only kind of holder that can contain Code pointers, so having a CodeObjectSlot is enough to compute the holder CodeDataContainer object and update the cached code entry point there. This CL fixes the data race in the previous implementation which were updating the code entry point during Code object migration.
