    [wasm] Refactor runtime functions for throw · 98966f56
    Clemens Backes authored
    We made two runtime calls: The first one allocated the exception object
    containing a FixedArray of exception values, the second call did the
    actual throw. Inbetween the code was filling the values array.
    This CL refactors this to only allocate the FixedArray initially, fill
    it, and then allocate the actual exception and throw it both from the
    second runtime function.
    This avoids a WasmGetOwnProperty call to find the values array.
