    [wasm] Add a "boolean validation" mode · 43f0f49d
    Clemens Backes authored
    All instantiations of the function body decoder (validation, Liftoff,
    TurboFan) currently generate precise error messages. For Liftoff though,
    the error message and location is never used. Thus we can save some
    binary size and performance by only keeping a flag whether an error
    occured or not. In the error case, the TurboFan compiler will execute
    right afterwards anyway, generating a proper error message.
    
    As as follow-up, we can avoid storing the pc in {ValueBase} and
    {ControlBase}, because that's only used for error reporting.
