C++: Fix decltype resolving for nested instantiated class

Browse Source 
The enclosingScope of a cloned nested class is not the
original class but the cloned parent.

Use-case:
template <typename T>
struct Temp
{
    struct Nested
    {
        static T f();
        typedef decltype(f()) type;
    };
};

struct Foo { int bar; };

void fun()
{
    Temp<Foo>::Nested::type s;
    s.bar; // bar not highlighted
}
