[llvm-dev] mini RFC: adding a tag for the SVN -> github migration

[James Y Knight via llvm-dev]

I really don't like that....I'd much prefer to resurrect the previous
discussion about tagging master after each release branch-point. Which I
*think* was generally agreed upon, except for a debate about what to CALL
those tags.

E.g., if we called `git merge-base origin/release/9.x origin/master`
"10_dev", then

$ git describe
10_dev-8276-g9671d1dc1764
