MDEV-7445: Server crash with Signal 6

Problem was in rewriting left expression which had 2 references on it. Solved with making subselect reference main.

Item_in_optimized can have not Item_in_subselect reference in left part so type casting with no check is dangerous.

Item::cols() should be checked after Item::fix_fields().

MDEV-7538: Wrong constraint (TINYINT or MEDIUMINT and INT)
causes server crash

Analysis: If wrong data types used on foreign constraint there
was possibility that foreign->id is NULL when incorrect
foreign constraint was removed from the dictionary cache.

Fix: Add guard foreign->id != NULL before trying to lookup
or remove the foreign constraint from dictionary cache.

Tested using user database where problem was repeatable.

Analysis: Purge thread does not have thd and no access to
handlerton.

Fix: If thd does not exists we use sql_print_warning instead
of push_warning_printf.
