    Reland "[offthread] Template deserializer on Isolate" · 6f898234
    Leszek Swirski authored
    This is a reland of e24fa913
    It fixes the heap verification errors by going back to using MakeThin
    instead of manually creating a filler (that then makes the verifier
    think that this was array left-trimming).
    
    Original change's description:
    > [offthread] Template deserializer on Isolate
    >
    > Make the deserializer class templated on Isolate/LocalIsolate. This
    > allows the ObjectSerializer to be split into a main-thread and offthread
    > variant, with the latter taking a LocalIsolate.
    >
    > Eventually, we probably want to anyway split off the code-cache de/serializer
    > to a separate implementation (for various reasons), and this the only one that
    > wants off-thread finalization, and at this point the deserializer can revert
    > back to being un-templated, used only for bootstrapping. However, this is the
    > simplest way, for now, to enable off-thread deserialization.
