Reverse order of `-Zinput-stats` and `-Zmeta-stats` output.

Currently they have the largest items at the end. I believe the
rationale is that it saves you scrolling up through terminal output
because the important stuff is at the bottom. But it's also surprising
and a bit confusing, and I think the obvious order (big things at the
top) is better.
