evgen@moonbone.local 4f4711bd49 Fix bug#13356 resolve_const_item() wasn't able to handle Item_row items. ...

resolve_const_item() assumed to be not called for Item_row items. For
ensuring that DBUG_ASSERT(0) was set there.

This patch adds section for Item_row items. If it can it recursively calls
resolve_const_item() for each item the Item_row contains. If any of the
contained items is null then whole Item_row substitued by Item_null. Otherwise
it just returns.
