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

Start with the benchmark source in src/benchmarks/micro/runtime/Exceptions/Handling.cs, especially the listed ranges around lines 60-77, 194-211, 226-243, and 494-509. Compare the baseline and test results for the Linux/x64 Ubuntu 22.04 run, then determine which of the 13 reported improvements has an actionable runtime change; completion is not defined by the issue.
