Fails to resolve dependent name type

[jslee02]

chimera fails to resolve clang::DependentNameType such as typename S::Scalar in the following code:

template <typename T>
class Vector {
public:
  using Scalar = T;
};

template<typename S>
struct ScalarTrait {
  typedef typename S::Scalar type;
};

using VectorScalar = ScalarTrait<Vector<double>>::type;

that throws an exception as

chimera.util.resolveDeclaration:1:18: error: use of undeclared identifier 'S'
typedef typename S::Scalar chimera_placeholder_4;
                 ^
chimera.util.resolveDeclaration:1:21: error: expected a qualified name after 'typename'
typedef typename S::Scalar chimera_placeholder_4;
                    ^
chimera.util.resolveDeclaration:1:27: error: expected ';' after top level declarator
typedef typename S::Scalar chimera_placeholder_4;

This is suppressed by #329, but it needs to be resolved correctly.
