    Add UtilityReturnsTuples() support for CALL

    This ensures that prepared statements for CALL can return tuples.

The change whether a statement returns tuples or not causes some
different paths being taking deep in the portal code that set snapshot
in different ways.  I haven't fully understood them yet.  I plan to post
more tomorrow.
