[PATCH] D148123: [AArch64][CostModel] Make sext/zext free if folded into a masked load

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

That would make sense for normal loads, but masked loads will not split like that (unless they can extend the mask). https://godbolt.org/z/x9T8vP6Kx. It may be simpler to be more precise about the cost if it returned it directly.
