[Shootout-list] Sorting on the side-by-side page

[Alan Post]

In the side-by-side, the sorting is slowest-to-fastest, whereas in the
benchmark page, the sorting is fastest-to-slowest.

I like the fastest-to-slowest sorting in the benchmark page, because
there are lots of slow languages that I'm not interested in.  I think
the side-by-side page should be sorted the same as the benchmark page.
