When unqualified name lookup finds a type within a base class, substitute the generic arguments used for the base.

Previously, unqualified name lookup that resolved to a type in a base
class would simply produce the type, which might still involve
archetypes if the base class were generic. Substitute the generic
arguments used in that specialization (say, if EmployeeList inherites
Vector<Employee>) into the member type. Fixes <rdar://problem/12938561>.
