[PATCH] Generate better code for shuffles

[Michael Kuperstein]

The line-endings get cleaned up on submission, thankfully.

Regarding the miscompile - yes, that's what I thought. Wasn't sure it was a miscompile, or some magic is going on behind the scenes, but avoided it anyway since generating "unaligned" extracts didn't make sense to me from a performance stand-point.

Regarding http://reviews.llvm.org/D6622 - it's good to hear I didn't miss anything. I'll add the test-case from http://reviews.llvm.org/D6622 to my commit.
