Some improvements to -Zinput-stats and -Zmeta-stat inspired by the new -Zmacro-stats.

r? @lqd

Taking inspiration from -Zmacro-stats:

Use "{prefix}" consistently.
Use names for column widths.
Write output in a single eprint! call, in an attempt to minimize interleaving of output from different rustc processes.
Use repeat for the long --- banners.

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.

To make it match -Zmacro-stats, and work better if you have enabled it for multiple crates.
