I know -- they aren't actually different versions.
The svn revisions in the filenames are the "Last Changed Rev:" ID from svn
(so they will always be close but never the same).

While we could just take the "Revision:" ID instead and get identical
numbers, I preferred to look at the last changed rev because it makes it
easier to spot in what build something actually changed (e.g. if I'm
looking for a fix for a clang problem and I see only the LLVM revision has
increased, I know I don't have to check the newer build).

Not sure if my reasoning there makes sense - there's obviously also reasons
to just go with the "Revision:" ID...
