+Summary: We generate invalid IL for the access of static readonly fields in ctors
+
+In this code:
+using System;
+
+class T {
+	static readonly DateTime Foo = new DateTime (1900, 1, 1);
+	
+	public T ()
+	{
+		Console.WriteLine (".ctor (): " + Foo.Ticks);
+	}
+	
+	static void Main ()
+	{
+		Console.WriteLine ("Main (): " + Foo.Ticks);
+		T t = new T ();
+	}
+}
+
+For the .ctor we generate:
+
+IL_000b:  ldsflda  valuetype [mscorlib]'System.DateTime' 'T'::'Foo'
+IL_0010:  call instance int64 valuetype [mscorlib]'System.DateTime'::'ge
+t_Ticks'()
+
+While for the static method we generate:
+IL_0005:  ldsfld  valuetype [mscorlib]'System.DateTime' 'T'::'Foo'
+IL_000a:  stloc.1
+IL_000b:  ldloca.s 1
+IL_000d:  call instance int64 valuetype [mscorlib]'System.DateTime'::'ge
+t_Ticks'()
+
+The code for the ctor is invalid. You cant load the address of a readonly
+field except for in a .cctor. PEVerify complains about this.
