It's not about what we want — there's simply no way to know which SVN revision
of LLVM we're building against. So it's not possible for Mesa to work with LLVM
SVN snapshots both before and after incompatible API changes. All we can try to
ensure is that current Mesa Git master works with current LLVM SVN trunk.
