Interesting article! Just one thing:
Isn't it "begun" in "The work on the loop vectorizer had just began"?

Will there be a benchmark of this soon? As I understand it loop vectorization can net big performance gains.

Correct. The other way that begun would be properly used would be to say, ``Work has begun on the loop vectorizer ...''

I'll be sure to ask on the thread in question once Nadav, Hal Finkel, Chris Lattner and others intimately involved have worked out more of it.

Catching up on the discussion it appears the next LLVM Meeting they are planning on a BoF to discuss the Loop Vectorizer in-depth and to target their goals more completely.
