In the failing case (see test), the loop variable (which should be context
allocated) is in a hidden scope, so we need to save and restore data for hidden
scopes too.
The !is_hidden() check was overly limiting - NeedsScopeData already handles the
"hidden leaf scope" case which is the one we want to avoid.
(Btw, this also means that the previous assumption "variables in hidden scopes
are not context allocated" was wrong.)
