GetTypeInfo() should return the inferred delegate type for method groups

[cston]

GetTypeInfo() should return the inferred delegate type for method groups - for the initializer of d1 for instance.

What should GetTypeInfo() return for the initializer of d2 since we don't need to infer a delegate type for that expression?

using System;

delegate void D();

class Program
{
    static void Main()
    {
        Delegate d1 = Main; // System.Action
        D d2 = Main;        // D?
    }
}

Relates to "lambda improvements" feature (test plan)
