Avoid TLS access for groupUpdateData
By putting the groupUpdateData pointer into the same thread local as the
binding status, we avoid having to fetch two thread_local variables.
Moreover, we can reuse the caching mechanism which we have in place for
QBindingStatus to avoid costly TLS lookups.
Pick-to: 6.2
