Research direction

Start with the benchmark source at src/benchmarks/micro/libraries/System.Runtime.Intrinsics/Perf_Vector128OfT.cs, especially the linked lines for the reported operations. Compare the baseline and test reports linked in the issue, then determine whether the improvement requires a follow-up change; the issue provides no specific implementation target or completion criteria.
