Typed array as IList and indexing

[GoogleCodeExporter]

If you return a typed array from a general method as an IList then indexing 
will fail. The underlying typed array doesn't support the getter and setters 
that will be generated e.g.

        public static void ArraysAsIListT()
        {
            IList<int> ints = new[] {1, 2, 3};

            ints[0] = 4;
            var val = ints[2];

        }

generates

        ArraysAsIListT: function ()
        {
            var ints = new Int32Array([1, 2, 3]);
            ints.set_Item$$Int32(0, 4);
            var val = ints.get_Item$$Int32(2);
        }

Which errors with:

Uncaught TypeError: Object #<Int32Array> has no method 'set_Item$$Int32'

This code adds support for IList in native arrays:

    [JsType(JsMode.Prototype, Name="Array", OmitDefaultConstructor=true, NativeOverloads=false)]
    class JsArrayExtensions<T> : JsArray<T>
    {
        public T this[int index]
        {
            get { return this.As<JsArray<T>>()[index]; }
            set { this.As<JsArray<T>>()[index] = value; }
        }
    }
