I think I've mentioned this before but internally we are (mostly) using
"rev-list --count --first-parent branch-name" which gives us a
monotonically increasing number per-branch. The --first-parent means
each merge counts as one, which is enough for build-number uniqueness.
Unique sequential build numbers meet our internal needs. If this number
gets incorporated into the version numbering self-reported by Clang/LLVM,
then it's not hard to map back onto git commits.
