   FWIW I tested this branch with a local micro benchmark I had and it shows significant improvement. I wrote up some details here: https://docs.google.com/document/d/15DRpIr1EUqo7zVR1psBhoX95ML1PO55kkHwt2EasM88/edit#heading=h.pfa677dojqtv
   
   Backstory was I was looking at the performance of these kernels (inspired by @rdettai ) as `utf8_neq_scalar` came up in a talk I was giving last week. What a wonderful surprise that there is a PR actively improving them (and it happens to also fit the narrative of my talk well!)
