For Apache and Dhrystone, the performance boost is good (but only the
former is really important), but for the rest, especially those with
image/sound processing, and HMMR, it's still far behind. Is this only
because there is no auto vectorization in LLVM?

Would be good to know why some programs were not compiled with Clang.
