[PATCH] D125194: [SVE][SelectionDAG] Use INDEX to generate matching instances of BUILD_VECTOR.

[Paul Walker via Phabricator via llvm-commits]

paulwalker-arm updated this revision to Diff 438408.
paulwalker-arm added a comment.

Extended to allow an arbitrary start index.

I'm posting this update for comment but it is my intention to split the patch because the findMoreOptimalIndexType change is not great and better done without needing `isConstantSequence`.
