[PATCH] D141602: [TTI][AArch64] Cost model insertelement and indexed LD1 instructions

[Sjoerd Meijer via Phabricator via llvm-commits]

I am struggling with my motivating example for the SLP vectoriser. There are multiple things going on, and this doesn't seem to make a difference.
So for now, this "looks more correct" to me as index LD1s are expensive. If you're not convinced, I am happy to park this for now.
