Can not plan scans with complex ordering expressions

[hatyo]

If we have a SQL statement like the following:

select a & 1, a & 2 from t order by a & 1, a & 2

The planner is not able to plan it, even if we have a matching value index:

create index idx1 as select a & 1, a & 2 from t1 order by  a & 1, a & 2
