      [zone-stats] Implement collecting per-object-type zone stats · 627b8781
      Igor Sheludko authored
      ... behind --trace-zone-type-stats flag.
      
      Per-object-type statistics requires the following GN args:
        v8_enable_precise_zone_stats = true
        use_rtti = true
      
      When precise zone stats is enabled, the used zone memory value is
      calculated more precisely, in particular it takes into account
      the state of the active segment. By default, the used memory in
      the active segment is not taken into account because of performance
      overhead.
