Summary: For Incremental LTO, we need to make sure that an old cache entry is not used when incrementally re-linking with a new libLTO. Adding a global LLVM_REVISION in llvm-config.h would for to rebuild/relink the world for every "git pull"/"svn update". So instead only libLTO is made dependent on the VCS and will be rebuilt (and the dependent binaries relinked, i.e. as of today: libLTO.dylib and llvm-lto).
