[swift-dev] problems building swift-3.0-RELEASE

[Jon Rafkind]

Sorry this was user error. Somehow I didn't have either llvm or clang 
checked out to swift-3.0-RELEASE before I started the build.

It would be great if update-checkout were changed to run 'git pull 
--tags', I think. I tried adding it to the script myself but I got some 
obscure git error.
