    cppgc: Remove the 2GB split · 411cd56d
    Anton Bikineev authored
    The split is rudimental and now is not needed at all:
    - as part of the shared-cage effort we added HeapHandle pointer to the
      BasePageHandle class (on the API side);
    - for the value-full barrier we get HeapHandle from bitmasking the
      value;
    - for the value-less barrier we get it from the callback provided by the
      caller.
    
    The CL entirely removes the split and uses the single
    BoundedPageAllocator. A minor note: the conservative stack scanning can
    become sligthly more expensive.
