Expand allowed order by expressions

Key: TEIID-3253
URL:
https://issues.jboss.org/browse/TEIID-3253
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.10
with a non-simple query we won't allow derived expressions in the order by such as:
select max\(x), y from t group by y order by case when y is null then 0 else y end
We treat this ordering as unrelated - however it is expressed in terms of expressions
from the select clause. Mondrian will generate queries of this form, which requires a
workaround of modifying the dialect to use ansi null ordering.
