    [builtins] Use the ElementsAccessor to copy TypedArrays. · 356e9246
    Peter Marshall authored
    This includes a fastpath in the ElementsAccessor for the source
    array being a JSArray with FastSmi or FastDouble packed kinds. This
    is probably a pretty common usage, where an array is passed in as
    a way of initializing the TypedArray at creation (as there is not other
    syntax to do this). e.g. new Float64Array([1.0, 1.0, 1.0]) for some
    sort of vector application.
