    [wasm] Avoid embedding {null} values in WasmCode. · fabb5140
    Michael Starzinger authored
    This loads references to {null} values from the instance object instead
    of embedding them into the generated code. It is one step towards making
    the {WasmCode} objects independent of the Isolate.
    
    Note that this also fixes an issue with the serializer/deserializer that
    failed to properly serialize {null} values and accidentally collapsed
    them to {undefined} values instead.
