Currently 13.x has a "memory tag read" command and half the supporting code for
"memory tag write". Backporting the following patches would complete the tag
write command, and the basic memory tagging feature set for lldb 13.

Ok to cherry pick these to the branch?

Also I'd like to add these features to the lldb release notes. Can I do that
directly or should I put up a phabricator review for it first?
