[PATCH] D104538: [CostModel][AArch64] Improve cost model for vector reduction intrinsics

[Sjoerd Meijer via Phabricator via llvm-commits]

Nice one. This work was motivated by a missed opportunity in the SLP vectoriser. 
Can you separately create a reduced test case for that, so that we can first precommit that?
Then, that tests should be modified here.
