Bug Description
Using unions inside views inside subqueries causes non-matching rows to be returned in maria-5.3-mwl89. Not repeatable in maria-5.3.
SET SESSION optimizer_switch = 'in_to_
CREATE VIEW v1 AS SELECT 2 UNION SELECT 2 ;
SELECT 'bug' FROM DUAL WHERE ( 5 ) IN ( SELECT * FROM v1 ) ;
In this case, the IN predicate in the WHERE is obviously FALSE, however the 'bug' row is still returned.

MWL#89
- Auto-merge with 5.3 main.
- Changed the test for LP BUG#719198 so that
an two more queries were added, and removed a
query that produces a wrong result due to an
unrelated problem. The wrong result is submitted
as a separate bug.
