Remove test assertion checking that different random seeds lead to different code motion decisions. This was the case for the specific pair of random seeds, IR fed to code motion, and target platforms tested originally; but does not need to hold in general. Remove similar test assertion in IGVN randomization test case. Re-enable the test case. Reviewed-by: shade, kvn
