paulherman added a comment.
The need for ParseDeclsInContext is to get a list of namespaces that are contained within a using-directive. This does not actually parse anything but DW_TAG_imported_namespace and DW_TAG_imported_decl. The actual contents of the namespace are parsed only when the search reaches it.
About having the using-directives in the source that is passed to clang, I don't think that will work since there is a comment in ClangASTSource::FindExternalDeclsByName:
// Using directives found in this context.
// Tell Sema we didn't find any or we'll end up getting asked a *lot*.
