Neeraj Bisht 65af83f642 Bug#11758009 - UNION EXECUTION ORDER WRONG ? 
Problem:-
In case of blob data field, UNION ALL doesn't give correct result.

Analysis:-
In MyISAM table, when we dont want to check for the distinct for particular 
key, we set the key_map to zero.

While writing record in MyISAM table, we check the distinct with the help 
of keys, by checking whether that key is active in key_map and then writing 
the record.

In case of blob field, we are checking for distinct by unique constraint, 
where we are not checking whether that unique key is active or not in key_map.

Solution:-
Before checking for distinct, check whether any key is active in key_map.

storage/myisam/mi_write.c:
  check whether key_map is active before checking distinct.
