[PATCH] D115143: [AArch64][Analysis] Add on overhead costs for SVE gathers and scatters

[Sander de Smalen via Phabricator via llvm-commits]

There's probably more follow-up work to fine-tune this, but the patch seems like a slam-dunk win overall, as this patch significantly reduces any regressions we found when running this on a series of benchmarks.
I like @dmgreen's suggestion to make this a tuneable option because it makes it easier to experiment with other g/s costs.
