    Original commit message:

    [snapshot] Do not defer ArrayBuffers during snapshotting

    ArrayBuffer instances are serialized by first re-assigning a index
    to the backing store field, then serializing the object, and then
    storing the actual backing store address again (and the same for the
    ArrayBufferExtension). If serialization of the object itself is deferred,
    the real backing store address is written into the snapshot, which cannot be
    processed when deserializing, leading to a crash.

    This fixes this by not deferring ArrayBuffer serialization and adding a DCHECK
    for the crash that previously occurred.

  3. deps: V8: backport 22014de00115 

    Original commit message:

    Reland "[snapshot] rehash JSMap and JSSet during deserialization"

    This is a reland of 8374feed55a5b3010f2e9593560a2d84f9f6725f.

    Fixed rehashing of global proxy keys by creating its identity hash
    early, before the deserialization of the context snapshot.

    Original change's description:
    > [snapshot] rehash JSMap and JSSet during deserialization
    >
    > To rehash JSMap and JSSet, we simply replace the backing store
    > with a new one created with the new hash.
