- Add a new broker mode kRetired, in which the heap can again be accessed. - Change the way modes work. We now always start in kDisabled. If FLAG_concurrent_compiler_frontend is on, we eventually move to kSerializing, then to kSerialized, then to kRetired. - Add an ObjectDataKind to ObjectData that indicates whether the data is just a dummy (i.e. created while broker was in kDisabled mode). This also happens to fix a bug found by clusterfuzz.
