Review checklist: suggest checking insertions expected to be new. (#7245)
Suggest checking that PRs assert that insertions into sets or maps
expected to be adding new values didn't actually just replace some
existing value.

Bug #7048 and its several duplicates would have been caught sooner if
the insertion of the new spill temporary into the `spilled_composites`
table had asserted that there was no existing spill variable for that
expression.
