Method generic type parameters are out of parameter list scope for 'nameof' expression

[controlflow]

[A(nameof(U))] // ok
class Test<U> {
  void M<T>(
    T t = default(T), // ok
    string s = nameof(T) // error CS0103: The name 'T' does not exist in the current context
  ) { }
}

class A : System.Attribute {
    public A(string s) { }
}

It compiles as expected in CTP4, but fails in current 'master'. Maybe related to #40.

According to "nameof operator - v5", it should work.

And it works for U.

[controlflow]

Ugh, according to examples from v5 spec, maybe this is not a bug...

[Foo(nameof(T))] void f<T> { }
// result error "T not defined": A method type parameter is not in scope in an attribute on that method

void f([Attr(nameof(x))] int x) {}
// result error "x is not defined": A parameter is not in scope in an attribute on that parameter, or any parameter in the method

Accidentally closed the issue :/
