Here's my proposal:
- Release branches will be named: release/3.5.x (for old version numbering
scheme), release/7.x (for new).
- The tags for release branches will be named v8.0.0 (for final), and
v8.0.0-rc1 for release candidates.
- Tags on the master branch (which will be created at commits modifying the
version file after branch creation, ala r338537) will be named v8.0.0-dev.

I don't feel terribly strongly about whether to use "llvm-8.0.0" or

The "v8.0.0" style seems to be very widely used, so that'd still be my
inclination, barring a good reason why we shouldn't. The other scheme I've
seen commonly is actually just the raw version, e.g. "8.0.0" without any
prefix at all.

I'll note that there is at least one minor advantage to using one of
"v8.0.0" or "8.0.0". Github can make download tarballs/zipfiles from
release tags, and when doing so, will name the file "$repository-$name.zip"
(if you're downloading a tag or branch), or "$repository-$commithash.zip"
otherwise. For tag names, it also strips "v" prefix in front of a version
number, if you had one.  So, with either of the usual schemes, we'd get an
automatically-generated filename of "llvm-8.0.0.zip". Instead of, say,
"llvm-llvm-8.0.0.zip" if we were to go with a tag named "llvm-8.0.0". That
said -- the LLVM project probably isn't going to use those for our official
release distributions, so I think that advantage doesn't really matter.
