[Benchmarking workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/benchmarking-workflow-dotnet-runtime.md)

Start with the benchmark source at src/benchmarks/micro/libraries/System.Numerics.Tensors/Perf_BinaryIntegerTensorPrimitives.cs#L31-L32 and review the LeadingZeroCount benchmark for Int32 with BufferLength 3079. Run the provided benchmarks_ci.py command and compare the reported result with the linked baseline and test reports. Done means the improvement is understood and the issue has a concrete follow-up or triage outcome.
