222a384a06 On an UPSERT when the order of constraint checks is rearranged, make sure 
that the affinity transformations on the inserted content occur before
any of the constraint checks.  Fix for ticket [79cad5e4b2e219dd197242e9e5f4e].

fef37760da Identify Select objects within a single statement using small sequential

on successive runs.
