Research direction

Start with the benchmark sources src/benchmarks/micro/runtime/Math/Functions/Single/Min.cs, Single/SinPi.cs, Double/Min.cs, and src/benchmarks/micro/runtime/BilinearInterpol/BilinearInterpol.cs, then run the listed benchmarks_ci.py commands. Review the linked test reports and profiling/benchmarking workflow docs; the payload does not define a requested change or completion condition.
