For equal cascadenumbers for an urgent eviction, canEvictInterferenceBasedOnCost couldreturn success. The actual eviction would then hit this assert. Avoidever returning true for equivalent cascade numbers.The resulting failed allocation seems a bit off to me. e.g. inillegal-eviction-assert.mir, I wuold assume %0 gets allocated startingat $vgpr0. That was its initial allocation choice, but was laterevicted. In this example no evictions can help improve anything.
