Combined fix for MDEV-7267 and MDEV-8864
...
The problem was that GROUP BY code created Item_field objects
that referred to fields in the temp. tables used for GROUP BY.
Item_ref and set_items_ref_array() call caused pointers to temp.
table fields to occur in many places.
This patch introduces Item_temptable_field, which can handle
item->print() calls made after the underlying table is freed.
