This is a simple fix that brings the compilation time from 5min to 5s on a specific real-world example. It's a large chain of computation in a crypto routine (always a problem for SCEV). A unit test is not feasible and there would be no way to check it. The fix is just basic good practice for dealing with SCEVs, there's no risk of regression.
