Fixed LP bug #874378.
This bug happened for the queries over multi-table mergeable views
because the bitmap TABLE::read_set of the underlying tables were not
updated after the views had been merged into the query.
Now this bitmaps are updated properly.
Also the bitmap TABLE::merge_keys now is updated in prevention of
future bugs.
