    Reland of "[heap] Fine-grained JSArrayBuffer tracking" · b5704bc1
    mlippautz authored
    Track based on JSArrayBuffer addresses on pages instead of the attached
    backing store.
    
    Details of tracking:
    - Scavenge: New space pages are processes in bulk on the main thread
    - MC: Unswept pages are processed in bulk in parallel. All other pages
      are processed by the sweeper concurrently.
