Galina Shalygina 6c0f3dd341 MDEV-16090: Server crash in in Item_func_in::val_int or assertion `in_item' ...

failure upon SELECT with impossible condition

The problem appears because of a wrong implementation of the
Item_func_in::build_clone() method. It didn't clone 'array' and 'cmp_fields'
fields for the cloned IN predicate and this could cause crashes.
The Item_func_in::fix_length_and_dec() method was refactored and a new method
named Item_func_in::create_array() was created. It allowed to create 'array'
for cloned IN predicates in a proper way.
