    [turbofan] Prepare broker for the next steps. · bcbb6d9e
    Georg Neis authored
    - 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.
