Backporting the fix for pr103789 on the 11 branch revealed a lack of test
coverage for the tests provided with that fix.  Indeed, the tests use the KIND
argument of the respective intrinsics only with keyword arguments.
This adds variants with non-keyword arguments.

The tests enriched this way fail on the branch if the fix is cherry-picked
straightforwardly.  The fix will have to be tweaked slightly there.
