QualifiedTypeLoc does not store location information for the type
qualifiers. This is "intentional" but clearly not ideal for tooling clients
of type location information. Since the decl-specifiers for such a
declaration can be in any order, the source range for such a type isn't
necessarily going to be useful, and you may be able to get the information
you're looking for by just looking at the start location of the Decl.
