      Move kMaxRegularHeapObjectSize into globals · 059b5643
      mlippautz authored
      This way we avoid the cyclic dependency between objects.h and heap.h and still
      have one definition. Add a static assert that this size is indeed smaller than
      the payload of a page.
      
      Follow ups can finally remove the dependency on spaces.h for all heap.h users.

      [heap,snapshot] Replace first page size from snapshots with page trimming · ed8791ea
      mlippautz authored
      Replace first page size in the snapshots with a heap logic that trims pages
      after deserialization. The snapshot provided page sizes was just an
      approximation, while the heap knows exactly where to trim.
      
      Furthermore, trim the pages directly after deserialization, leaving no wiggle
      room for further objects. This avoids pollution of the immortal immovable pages
      with regular objects, e.g. Contexts. The downside is that we potentially require
      expanding the space with a new page.

      Track based on JSArrayBuffer addresses instead of the attached backing store.
      This way we can later on iterate buffers on a single page. The reland also
      switches to a page-based implementation where a page contains the set of its
      contained (live and dead) buffers.

      - Scavenge: New space pages are processes in bulk on the main thread
      - MC: Unswept pages are processed in bulk in parallel. All other pages

      [heap] Harden heap-related cctests · fdd9f6b9
      mlippautz authored
      - Move usable functions into proper heap-utils.h/.cc files and remove
        utils-inl.h file
      - Fix assumptions accross the board relying on certain behavior that is not
        invariant
      
      This is a requirement for modifying page size.
