[PATCH] D113003: [LoopVectorize] Enable tail folding for scalable vectors

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer added a comment.

Since we are (also) talking about profitability of the transform:

> For now it's best not to enable tail-folding with scalable vectors for low trip counts or when optimising for code size, since there has been no analysis on whether this is worth it.

I was expecting we would need to implement target hook `preferPredicateOverEpilogue` for AArch64/SVE that controls this, and add some of this logic there?
