[PATCH] Fix stack overflow in MSVC unqualified type lookup logic

[Reid Kleckner via cfe-commits]

Thanks for the patch and report!

Can this check be defeated with mutually recursive class template
inheritance? I was thinking something like this:

...
template <typename T, typename X>
struct FooWrapper : FooTemplated<T, X> { };

// Full template spec
template <class T, class X>
class FooTemplated : public FooWrapper<T, Bar> {
...

Maybe we should use a set of visited RDs?
