f35f2f92ed Move the generation of output column names earlier, to right after name 
resolution and before query transformations such as flattening.  This prevents
the names from getting mangled by query transformations, and obviates hacks
in the query flattener that attempt to work around the name mangling.
The resulting code is smaller and faster and gives more consistent output.
This is an alternative fix to ticket [de3403bf5ae5f72ed].

46133d98a6 Do not use the flattening optimization for a sub-query on the RHS of a LEFT 
JOIN if that subquery reads data from a virtual table. Because it prevents the
planner from creating an automatic index on the results of the sub-query, the
flattening optimization sometimes slows things down in this case.
