When importing C++ class template instantiations, Swift generates a type name for each instantiation. The generated names must be unique, since they are used for mangling. If multiple different C++ types declare nested types with the same name, which are then used as template arguments, Swift was generating the same name for those template instantiations (e.g. `shared_ptr<Impl>` for different `Impl` types). This change makes sure we use fully-qualified type names of template parameters when generating Swift type names for class template instantiations (e.g. `shared_ptr<MyNamespace.MyClass.Impl>`). This fixes an assertion failure coming out of IRGen: ``` Assertion failed: (Buffer.empty() && "didn't claim all values out of buffer"), function ~ConstantInitBuilderBase, file ConstantInitBuilder.h, line 75. ``` rdar://141962480
