    Description

      This script:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a BIGINT, b BIGINT UNSIGNED);
      		 
      INSERT INTO t1 VALUES (-9223372036854775808,18446744073709551615);
      		 
      SELECT * FROM t1 WHERE -1 IN (a,b);

      erroneously returns the row:

      +----------------------+----------------------+
      		 
      | a                    | b                    |
      		 
      +----------------------+----------------------+
      		 
      | -9223372036854775808 | 18446744073709551615 |
      		 
      +----------------------+----------------------+

      If I now change the left argument to DECIMAL or DOUBLE, it starts to work fine and return an empty set:

      SELECT * FROM t1 WHERE -1.0 IN (a,b);
      		 
      SELECT * FROM t1 WHERE -1e0 IN (a,b);

      CASE suffers from the same problem. See MDEV-11554.
