mariadb/mysql-test/main/having_cond_pushdown.test
Galina Shalygina ae15f91f22 MDEV-18769 Assertion `fixed == 1' failed in Item_cond_or::val_int 
This bug is caused by pushdown from HAVING into WHERE.
    It appears because condition that is pushed wasn't fixed.

    It is also discovered that condition pushdown from HAVING into
    WHERE is done wrong. There is no need to build clones for some
    conditions that can be pushed. They can be simply moved from HAVING
    into WHERE without cloning.
    build_pushable_cond_for_having_pushdown(),
    remove_pushed_top_conjuncts_for_having() methods are changed.

    It is found that there is no transformation made for fields of
    pushed condition.
    field_transformer_for_having_pushdown transformer is added.

    New tests are added. Some comments are changed.
