    Original change's description:
    > [compiler] Make NativeContextRef never-serialized
    >
    > Most NativeContext elements are immutable after initialization;
    > additionally, we now use acquire-release semantics to load/store
    > elements when possible. Reading and constructing Refs for elements
    > is thus possible from the background.
    >
    > A few notes:
    >
    > - A few elements are not immutable; if read from the background
    > thread, these must use acquire-release semantics.
    > - Elements can be stored from generated code; these are not compatible
    > with bg-thread accesses.
    > - While elements can be read safely from the native context, the
    > elements themselves may still require serialization; this is done in
    > NativeContextRef::Serialize.
