Added a failing test demonstrating the issue #451.

Uncomment the CompilerGeneratedAttribute, and the test will fail.

This attribute makes Settings class unresolvable.

By the way, the filter for CompilerGeneratedAttribute still allows registering anonymous classes, i.e.

// settings is compiler-generated
var settings = new
{
    Path = @"c:\System",
    AppName = @"command.com",
};

container.RegisterInstance<object>(settings, serviceKey: "settings");

// it works nonetheless :)
var x = container.Resolve<object>(serviceKey: "settings");
Assert.AreSame(x, settings);

Although it would be much more useful if anonymous classes could implement interfaces.

Yep.. works just great in scala or java.
