Add isIntersectionConstituent to relation key ( #34789 )
...
* Add isIntersectionConstituent to relation key
isIntersectionConstituent controls whether relation checking performs
excess property and common property checks. It is possible to fail a
relation check with excess property checks turned on, cache the result,
and then skip a relation check with excess property checks that would
have succeeded. #33133 provides an example of such a program.
Fixes #33133 the right way, so I reverted the fix at #33213
Fixes #34762 (by reverting #33213 )
Fixes #33944 -- I added the test from #34646
* Update comments in test
