No, I looked for benchmarks that target `is_permutation` but I couldn't find anything, maybe I missed it.
I just wanted to test my implementation so I made something basic by following the footsteps of other existing benchmarks (e.g. [mismatch](https://github.com/llvm/llvm-project/blob/c4ed0ad1f52a7bec7377bbaf75f812527ec739bd/libcxx/test/benchmarks/algorithms/mismatch.bench.cpp), [ranges_end_with](https://github.com/llvm/llvm-project/blob/c4ed0ad1f52a7bec7377bbaf75f812527ec739bd/libcxx/test/benchmarks/algorithms/ranges_ends_with.bench.cpp)).
