Support for TypeIdentifierAttribute

[yck1509]

In .NET 4, TypeIdentifierAttribute is used to indicate two COM interface should be treated as equivalent by runtime even if they're in different assemblies.

e.g.

        static void Main(string[] args) {
            var path = @"C:\Program Files\Reference Assemblies\Microsoft\VSTO40\v4.0.Framework\";
            var t1 = Assembly.LoadFile(path + "Microsoft.Office.Tools.Common.dll").GetType("Microsoft.Office.Tools.AddIn");
            var t2 = Assembly.LoadFile(path + "Microsoft.Office.Tools.Common.v4.0.Utilities.dll").GetType("Microsoft.Office.Tools.AddIn");
            Console.WriteLine(t1.IsEquivalentTo(t2));
            Console.WriteLine(t1.IsAssignableFrom(t2));
        }

When resolving member references, these type equivalence should be taken into account. I have some sample people sent to me that shows the problem with resolving. If you need it please tell me about it.

Please test latest commit. It passes my few tests, but I haven't tested a real world assembly yet.

It works for my case. I suppose it is fixed.
