We have to test for 'conds' here as the WHERE may not be constant
even if we don't have any tables for prepared statements or if
conds uses something like 'rand()'.
If the HAVING clause is either impossible or always true, then
JOIN::having is set to NULL by optimize_cond.
In this case JOIN::exec must check for JOIN::having_value, in the
same way it checks for JOIN::cond_value.
