Once we start the definition of an ObjCInterfaceDecl we won't attempt to ImportDeclContext later on. Unlike RecordDecl case which uses DefinitionCompleter to force completeDefinition we don't seem to have a similar mechanism for ObjCInterfaceDecl. This fix was needed due to a bug we see in LLDB expression parsing where an initial expression cause an ObjCInterfaceDecl to be defined and subsequent expressions during import do not call ImportDeclContext and we can end up in a situation where ivars are imported out of order and not all ivars are imported.
