[PATCH] D112236: [RISCV] Expand scalable vector bswap. Fix crash for bitreverse.

[Fraser Cormack via Phabricator via llvm-commits]

frasercrmck added a comment.

It's not very clear to me why we have different ways of expanding bswap. Why doesn't `VectorLegalizer::ExpandBSWAP` always call `TLI.expandBSWAP`, for instance?
