I think the issue is clang-specific. clang splits the standard notion of a dependent type into two separate bits, for the sake of diagnostics: `isDependentType()`, and `isInstantiationDependentType()`.  `isInstantiationDependentType()` reflects the actual standard definition of a dependent type; `isDependentType()` is a type that can actually vary across instantiations.
