[PATCH] D105994: [SVE] Add folds for sign and zero extends of vscale

[Dylan Fleming via Phabricator via llvm-commits]

DylanFleming-arm added a comment.

We could use the max-vscale attribute to determine if the runtime value fits the type. If this cannot be determined, the optimization would be skipped, otherwise we change the type of llvm.vscale to the extended type.
Would that be a suitable approach?
