#12076 does this for integer `/` and `%` by a scalar. An array more than half null takes `try_unary`, which iterates with `try_for_each_valid_idx`, for `Int32`, `Int64` and `UInt64`, and more than three quarters null for `UInt32`. The benchmark bot measured both paths at 20%, 50% and 90% nulls on Neoverse-V2 and on Xeon 8581C at the default target and at `x86-64-v3` ([Neoverse-V2](https://github.com/apache/arrow-rs/pull/12076#issuecomment-6639839111), [Xeon 8581C](https://github.com/apache/arrow-rs/pull/12076#issuecomment-6639832179), [`x86-64-v3`](https://github.com/apache/arrow-rs/pull/12076#issuecomment-6639833808)). Where the paths cross depended on both the type and the machine: below half null for the 64-bit types on x86, and above nine tenths null for `UInt32` on x86.
