Ok, so what happens for `expr Outer::Enum::var` is that LLDB will first resolve 
the `Outer` structure (and all its member fields, but not nested types). When 
clang looks for `Enum`, it wants to find it in a direct lookup into the `Outer` 
DeclContext. But that lookup will fail because we never created the decls for 
the nested type. There is no fallback to the external source in such a case 
unfortunately so LLDB never has the chance to correct this. See the 
`LookupQualifiedName` code path in `Sema::BuildCXXNestedNameSpecifier`.

So I think this proposed approach should be fine. But what I think could be 
better is if we just do the same for `DW_TAG_enumeration_type` and 
`DW_TAG_structure_type` as we do for `DW_TAG_subprogram`.

I.e., simply push back the type into `member_function_dies` (we should rename 
this) and then it will get resolved properly in `CompleteRecordType`.
