Do we have a rich enough CI API to recognize dependencies between 
repositories?  For example, if I create a local branch in my dmd 
repository named `fix_bug` and a local branch in my druntime 
repository also named `fix_bug` and submit both PRs to their 
corresponding repositories, can the CI scripts recognize that 
they have the same branch name and pull them both for testing?
