Running walltime benchmarks in CI is notoriously unstable, Introduce benchmarks that instead use instruction count and other more reproducible metrics, using `iai-callgrind` [1], which we are able to run in CI with a high degree of reproducibility. Inputs to this benchmark are a logspace sweep, which gives an approximation for real-world use, but may fail to indicate outlier cases. [1]: https://github.com/iai-callgrind/iai-callgrind
