Based on the current logic, objects of classes Item_func_charset and Item_func_coercibility (responsible for CHARSET() and COERCIBILITY() functions) are always considered constant. However, SQL syntax allows their use in a non-constant manner, such as CHARSET(t1.a), COERCIBILITY(t1.a). In these cases, the `used_tables()` parameter corresponds to table names in the function parameters, creating an inconsistency: the item is marked as constant but accesses tables. This leads to crashes when conditions with CHARSET()/COERCIBILITY() are pushed into derived tables. This commit addresses the issue by setting `used_tables()` to 0 for `Item_func_charset` and `Item_func_coercibility`. Additionally, the items now store the return values during the preparation phase and return them during the execution phase. This ensures that the items do not call its arguments methods during the execution and are truly constant. Reviewer: Alexander Barkov <bar@mariadb.com>
