MDEV-19245: Impossible WHERE should be noticed earlier after HAVING pushdownbb-10.4-galina
The bug appears because not all conditions are found to be knowingly
true or false in WHERE after HAVING pushdown optimization.
Impossible WHERE can be found much earlier compared with how it is done now.
To fix it and_new_conditions_to_optimized_cond() is changed.
