[PATCH] D63657: [benchmark] Change GetGitVersion to only check "dirty" when a tag is found

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

1. Can you just use something along the lines of `git describe --always --dirty` to avoid the `update-index`/`diff-index`?
2. Can you please either submit this upstream yourself, or explicitly state that it is okay to steal it from you and upstream (to avoid getting out of sync)
