Caveats: - Even though memtest is ISA-independent, it will only run for the Alpha builds, since there's no way to specify ISA-independent reference files and I didn't want to commit 3 copies since I'm not sure we want to run it for all the different ISAs anyway. - Reference outputs were generated on my laptop, so performance numbers will be low compared to zizzer. --HG-- extra : convert_revision : 210fe4abecc19fbab0b15402c6cb4863650bab66
