    Description

      This task is split from MDEV-36484 and proposes an alternative solution to the same problem. The test is the same:

      CREATE TABLE t1 (a INT);
      		 
      CREATE TRIGGER t1 AFTER INSERT ON t1 FOR EACH ROW INSERT INTO t1 VALUES (0);
      		 
      RENAME TABLE t1 TO c,v2 TO t;

      The description of the problem can be found in MDEV-36484 as well. In short: optimizer hints parser is sensitive to `thd->is_error()` set elsewhere. That behavior must be changed so it is only catches its own fatal errors
