It's not that hard to compute "no-data": non-RecordDecls are never no-data, RecordDecls are no-data if they don't have a vtable pointer (isDynamicClass()), and all fields are no-data.  We can save it in the CGRecordLayout.

Assuming that's the route we want to go, of course, as opposed to just making LLDB add no_unique_address markings to fields.
