-; This test aims to check ability to support "Arithmetic with Overflow" intrinsics

This relies on `CodeGenPrepare::combineToUSubWithOverflow` firing, however when encoding the int sizes we can do loop strength reduction before, which is preferable, but also means one no longer gets the overflow intrinsics inserted, hence the test is spurious. I think you mentioned elsewhere that it's risque to rely on specific optimisations, and since the correct lowering of the overflow intrinsics is already covered, this seems spurious, hence the removal.
