Worth keeping in mind they didn't do this because they think `clang` is better then the current `gcc` as far as compiling goes, they did it because they don't want to use `gcc` past version 4.3.0 since versions 4.3.0 and up are GPLv3. So this is more a comparison of the current `clang` vs. old `gcc` - obviously not much of a fair comparison.
