Thanks for uploading this. It does look very similar to the case I was looking at recently, but goes further than the optimization I was trying. (That was about altering `anyext(buildvector(..))`, not doing it earlier which looks like it allows the shuffles to lower more efficiently). I will try to take a look, to get my head around how this works.
