    [wasm] Do not serialize modules that don't contain TurboFan code · 272e5a87
    Andreas Haas authored
    The wasm serialization format only contains TurboFan code. All other
    functions are only represented by placeholders. With this CL
    serialization fails if the serialized module does not contain any
    TurboFan functions and would therefore consist only of placeholders.
    
    This is a defense in depth approach, because ideally serialization
    only gets triggered when TurboFan code is available. However, in some
    scenarios like debugging it can happen that modules without TurboFan
    code get serialized.
