    [wasm] Early compilation of import wrappers · b15b2c91
    Thibaud Michaud authored
    Compile import wrappers during module compilation by introducing import
    wrapper compilation units, the goal being to reduce instantiation time.
    
    For each wrapper, we assume the imported function is going to be a
    kJSFunctionArityMatchSloppy at instantiation time, which should be the
    most common case. If the function turns out to have a different kind the
    wrapper is going to be recompiled with the correct kind during instantiation.
