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

Start with the linked benchmark source in src/benchmarks/micro/libraries/System.Numerics.Tensors/Perf_FloatingPointTensorPrimitives.cs and review the Log(BufferLength: 128) result. Run the provided benchmarks_ci.py command to reproduce the WebAssembly measurement; the issue does not define a code change or completion condition, so triage must establish what should be done.
