[PATCH] [LoopVectorize]Teach Loop Vectorizer about interleaved memory access

[Renato Golin]

Hao, Adam, Michael,

I think this review has gone a bit too far for what it is. I agree there are still many points to cover and many issues to fix, but we should do them later, after the initial implementation is in. For what it is, a prototype for strided vectorization, this patch fits the bill. It's not on by default, it's still experimental and won't be used at -O3 or anything, so we're still safe in case it does miss-compile anything.

I'd like to thank Adam and Michael for the extensive comments, it's not easy to get passionate people to do code review. I'd also like to than Hao for his extreme patience with so many and so drastic code reviews! Finally thanks to Arnold and Nadav for the valuable input and discussions to get the first prototype working previously.

But right now, I think it's time we land this patch and continue the review on further patches.

Adam, if you're happy that Hao's last changes address your concerns, please approve the patch and let's start round 2 on a new review.

cheers,
