test code

System.Reflection.Emit.ParameterBuilder.SetConstant(System.Object defaultValue) behaves wrong compared to MS CLR. The problem is in wrong handling cases when Type of parameter described by ParameterBuilder is defined by System.Reflection.Emit.TypeBuilder object (not System.Type).

Maybe my explaination sounds is a bit confusing, so the problem is illustrated in the attached example code.

Affected version: master

Expected output:

Got output:
Exception: System.ArgumentException: Constant does not match the defined type.
  at System.Reflection.Emit.ParameterBuilder.SetConstant (System.Object defaultValue) [0x00000] in <filename unknown>:0 
  at SystemReflectionEmitParameterBuilderSetConstantTest.Main () [0x00000] in <filename unknown>:0 

Pull request with a patch & test case will follow soon at github.
