Pull request overview
Adds a new runtime flavor to the performance infrastructure to run CoreCLR microbenchmarks using a Composite R2R setup with interpreter fallback, including payload staging and pipeline wiring.
Changes:
- Add
coreclr_r2r_interpreterruntime type handling to build a Helix payload and pass the required BenchmarkDotNet arguments. - Introduce a new payload builder helper to stage a runtime pack + crossgen2 tool layout for R2R compilation.
- Wire a new Azure Pipelines job matrix toggle/job and bump BenchmarkDotNet nightly.
