drh 0af16ab2c2 Make sure that GROUP BY terms select input column names in preference to 
output column names, in compliance with the SQL standard.

drh e35463b312 Bare identifiers in ORDER BY clauses bind more tightly to output column name, 
but identifiers in expressions bind more tightly to input column names.
This is a compromise between SQL92 and SQL99 behavior and is what
PostgreSQL and MS-SQL do.  Ticket [f617ea3125e9c].

drh a3a5bd9b62 Only consider AS names from the result set as candidates for resolving 
identifiers in the WHERE clause if there are no other matches.  In the
ORDER BY clause, AS names take priority over any column names.
Candidate fix for ticket [2500cdb9be].
