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

[Dylan Fleming via Phabricator via llvm-commits]

DylanFleming-arm updated this revision to Diff 360544.
DylanFleming-arm added a comment.

Added check for vscale_range attribute before optimisation
If the attribute isn't present, or if the maximum value exceeds the bitwidth of the original instrinsic, the optimization is skipped

Updated .ll test to test the extra logic
