fca23557fe Reactivate query flattening when the result set of the outer query has 
no function calls or subqueries.  This is a partial reversal of 
check-in [c9104b59].  Co-routines are still preferred if the outer
query has a complex result set, but for simple results sets, query flattening
is used.  Check-in [4464f40ccd7] is completely backed
out due to this change.
