All found SUM items are added FIRST in the fields list and
we replace the item with a reference.
We also replace all functions without side effects (like RAND() or UDF's)
that uses columns as arguments.
For functions with side effects, we just remember any fields referred
by the function to ensure that we get a copy of the field value for the
first accepted row. This ensures that we can do things like
