Sergei Golubchik 798fcb5416 bugfix: cmp_item_row::alloc_comparators() allocated on the wrong arena ...

it used current_thd->alloc() and allocated on the thd's execution arena,
not on table->expr_arena.

Remove THD::arena_for_cached_items that is temporarily set in
update_virtual_fields(), and replaces THD arena in get_datetime_value().
Instead set THD arena to table->expr_arena for the whole  duration
of update_virtual_fields()
