Add a test that a method type parameter can be used in Nameof() in parameter default value in VB

[gafter]

In the review for the fix for #42, @AlekseyTs suggested we add an analogous test for the issue in VB. Specifically, we should test that a method's type parameters can be used inside a Nameof() expression in the default value for the method's value parameters.

It is possible that there is already such a test.

I can take a look at this.

@marstr That would be awesome!

Gah, wanted to assigned to @marstr. Need to get you added as a contributor.

[gafter]

@marstr Can you tell me when you expect to work on this?

[gafter]

The following should compile without error

Module Program
    Sub M(Of TP)(Optional name As String = NameOf(TP))
    End Sub
End Module

I'll get this finished by tomorrow morning. Should be easy enough :)

Code change is made, waiting for VS15CTP6 to install to run tests. I added this test in src/Compilers/VisualBasic/Test/Syntax/Parser/ParseDeclarationTests.vb with just under Generic Class Declaration tests. Seem appropriate?

[gafter]

We need it to not just parse, but also bind correctly. This should probably be be in symbol tests or binding tests. I suggest adding to the tests in NameOfTests.vb. Please add a test with an "expectedOutput".

[marstr]

Okay, will do!

[gafter]

@marstr Do you have a change I can pick up to complete this?

[marstr]

Gah, sorry I got side tracked and never finished this. I suppose it's for the best to have someone else pick this up.
