I realized that ccache -z clears out not only the global stats, but the
per-file cache stats (from which the global stats are derived) - which
obviously makes the cache work poorly.

Newer ccache has CCACHE_STATSLOG, and --show-log-stats, which I think
can do what's wanted.  I'll update my ci branch with that.
