Post-review fixes for bug #1790 'BIT_AND() result in GROUP BY different when
SQL_BIG_RESULT used':
- BIT_AND now returns BIGINT UNSIGNED
- in case there were no matching rows BIT_AND returns 18446744073709551615
(but not NULL), BIT_OR returns 0 (but not NULL). That's how Monty wants it
and how is described in our docs.
