      Reland "cppgc: Add page memory allocation backend" · 67ea6211
      Michael Lippautz authored
      This is a port of src/components/gc that was added recently.
      
      Differences:
      - Added back bucketing to the page pool, as that guarantees that
        arenas used for specific types do not have their pages used by other
        arenas.
      - Replaced base::flat_map with std::map. This may cause performance
        regressions when using PageMemoryRegionTree in hot paths. A
        vector-like representation may be used to fix such a regression
      
      This reverts commit a056cea5.

      cppgc: Add HeapObjectHeader · 0a64a52b
      Michael Lippautz authored
      This adds HeapObjectHeader, a meta object that is put in front of
      every managed object. HeapObjectHeader provides accessors for:
      1. GCInfoIndex
      2. In construction bit
      3. size
      4. Mark bit
      
      Meta info is distributed among two uint16_t fields as (1.,2.) and
      (3.,4.). This is convenient as the non-bit accessors (size,
      GCInfoIndex) are constant during marking.
      
      Object layout see heap-object-header.h.
      
      Note: The current implementation does not bypass ASAN poisoning and
      assumes an unpoisoned header whenever performing an access.
