Summary

This optimization yields some very interesting results in rootglob-heavy
repositories.

I build a test repository of the following structure:

root
    /<uuid>/build/empty_file
    ... repeat for 4000 entries

and a .hgignore containing the corresponding 4000 rootglob entries pointing
to all build/ folders.

Rust+c hg status goes from 350ms down to 110ms.
