-; Test that SCEV gets invalidated when one of its dependencies is invalidated.
-;
-; Each of the RUNs checks that the pass manager runs SCEV, then invalidates it
-; due to a dependency being invalidated, and then re-urns it. This will
-; directly fail and indicates a failure that would occur later if we ddidn't
-; invalidate SCEV in this way.
