    [wasm] Adjust EstimateNativeModuleCodeSize to dynamic tiering · ea8da506
    Andreas Haas authored
    With dynamic tiering, the total amount of code generated for a
    WebAssembly module decreases significantly. However, the amount of
    code space we reserved for generated code has not been adjusted yet.
    This CL adds a parameter for dynamic tiering to
    EstimateNativeModuleCodeSize. If dynamic tiering is used, then the code
    space reserved for TurboFan gets reduced to a quarter of the code space
    without dynamic tiering.
    
    Reserving a quarter of the space seems to be still quite generous. Even
    Google Earth, seems to use a lot of its code, only needs less than 20%.
