+ @param keyuse Evaluated KEYUSE structure
+
+ @details
+ This function is supposed to be used after the best execution plan have been
+ already chosen and the JOIN_TAB array for the best join order been already set.
+ For a given KEYUSE to access this JOIN_TAB in the best execution plan the
+ function checks whether it really can be used. The function first performs
+ the check with access_from_tables_is_allowed(). If it succeeds it checks
+ whether the keyuse->val does not use some fields of a materialized semijoin
+ nest that cannot be used to build keys to access outer tables.
+ Such KEYUSEs exists for the query like this:
+ select * from ot
+ where ot.c in (select it1.c from it1, it2 where it1.c=f(it2.c))
+ Here we have two KEYUSEs to access table ot: with val=it1.c and val=f(it2.c).
+ However if the subquery was materialized the second KEYUSE cannot be employed
+ to access ot.
+
+ @retval true the given keyuse can be used for ref access of this JOIN_TAB
+ @retval false otherwise
