How is this any different then the buildbots displaying the revision  
tag for a build that works? And the definition of "works" I assume you  
mean build and make check cleanly. llvm-test is a different beast and  
you need to compare from one run to the next because we do not  
currently pass for everything (which is the job of the nightly tester  
in theory).

Also, llvm.org is severely strained right now. We are upgrading the  
server but I need a few weeks for this. If its possible, it would be  
nice to have the buildbots update and not do a full check out.
