Hm. Perhaps cfbot could just use the sorting from cirrus? I don't really like
the idea of making the names more confusing with numbered prefixes,
particularly when only used for some but not other tasks.

I don't think that'd really make anything worse. But perhaps we could just
reduce the CPU count for linux autoconf by 1? I suspect that even with asan
enabled it'd still be roughly even with the rest.

I'll try to repost a version of the ubsan/asan patch together with the
sanitycheck patch and see how that looks.
