For this particular case! Scott is testing ooo architectures, which
generally do not benefit that greatly from scheduling anyway. The picture
is wholly different with in-order archs where pre-regalloc scheduling can
make a horribly high difference (if it's given that there is a reasonable
number of registers, so that scheduling does not interfere with regalloc
that much).
