Igor Babaev 1fde449f1d MDEV-16820 Lost 'Impossible where' from query with inexpensive subquery
This patch fixes another problem introduced by the patch for mdev-4817.
The latter changed Item_cond::fix_fields() in such a way that it could
call the virtual method is_expensive(). With the first its call
the method saves the result in Item::is_expensive_cache. For all next
calls the method returns the result from this cache. So if the item
once was determined as expensive the method always returns true.
For subqueries it's not good, because non-optimized subqueries always
is considered as expensive.
It means that the cache should be invalidated after the call of
optimize_constant_subqueries().

MariaDB is designed as a drop-in replacement of MySQL(R) with more
features, new storage engines, fewer bugs, and better performance.

MariaDB is brought to you by the MariaDB Foundation.
Please read the CREDITS file for details about the MariaDB Foundation,
and who is developing MariaDB.

MariaDB is developed by many of the original developers of MySQL who
now work for the MariadB Foundation and the MariaDB Corporation, and by many people in
the community.

MySQL, which is the base of MariaDB, is a product and trademark of Oracle
Corporation, Inc. For a list of developers and other contributors,
see the Credits appendix.  You can also run 'SHOW authors' to get a
list of active contributors.

A description of the MariaDB project and a manual can be found at:

https://mariadb.com/kb/en/mariadb-versus-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/

As MariaDB is a full replacement of MySQL, the MySQL manual at
http://dev.mysql.com/doc is generally applicable.
