GH-118095: Unify the behavior of tier 2 FOR_ITER branch micro-ops (GH-118420)

* Target _FOR_ITER_TIER_TWO at POP_TOP following the matching END_FOR

* Modify _GUARD_NOT_EXHAUSTED_RANGE, _GUARD_NOT_EXHAUSTED_LIST and _GUARD_NOT_EXHAUSTED_TUPLE so that they also target the POP_TOP following the matching END_FOR
