Research direction

Start with the benchmark source at performance/src/benchmarks/micro/libraries/System.Numerics.Vectors/Perf_Matrix4x4.cs, especially the listed Matrix4x4 benchmarks, and compare the baseline and test commits and reports. The issue provides no requested change or acceptance criteria, so completion cannot be determined until the performance result is triaged.
