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.
