Nicholas Nethercote 9a926e5d6c Fix metadata stats.
This commit:
- Counts some things that weren't being counted previously, and adds
  an assertion that ensure everything is counted.
- Reorders things so the `eprintln`s order matches the code order.
- Adds percentages, and makes clear that the zero bytes count is orthogonal to
  the other measurements.

Example of the new output:
