Spectral-norm: Change / 2 into * 0.5 to see the impact on nightly testing

[trivial, not reviewed, suggested by @ronawho]

Elliot was curious what would happen if we changed / 2[.0] into * 0.5
in spectral-norm. On my Mac, it looked like a wash, but did turn in the
best time I've seen so far (but Macs are noisy), so checking this in to see
what happens in the nightlies.

While here, I got the comment correct and changed a 0..#n into 0..<n
which is my current preferred form.
