MDEV-28620, MDEV-28621, MDEV-28622 Server crash in /sql/item_subselect.cc *bb-10.3-MDEV-28622
Optimizer has eliminated subquery for various reasons.
Attempting to walk or access Item_subselect (and descendents)
values causes issues for these removed Items. Fixed by setting
either fixed_const, null_value or checking eliminated.
