    [sandbox] Fix serialization of raw external references · 63e054f5
    Samuel Groß authored
    When testing the serializer (e.g. via --stress-snapshot), raw external
    references (i.e. just raw pointers) can be embedded inside the snapshot.
    When those pointers are sandboxed, the corresponding external pointer
    tag also needs to be encoded in the snapshot. This CL adds the necessary
    logic to support this by introducing new serializer Bytecodes for raw
    external references and encoding the raw pointers together with the tag.
