 Fixed #33768 -- Fixed ordering compound queries by nulls_first/nulls_last
 on MySQL.

 Columns of the left outer most select statement in a combined query
 can be referenced by alias just like by index.

 This removes combined query ordering by column index and avoids an
 unnecessary usage of RawSQL which causes issues for backends that
 specialize the treatment of null ordering.
