About
The fotonik3d benchmark in spec2017 is reasonably friendly for vectorization, performance gains relative to a single FPU scalar implementation should be on the order of 12%. Verify the benchmark vectorizes and sees a comparable performance improvement on RISC-V.

- We're seeing roughly a 46% reduction in dynamic instruction counts. This is far higher than the performance improvements seen on other targets
- x86_64 sees a 17% performance improvement from vector
- aarch64 sees a 10% performance improvement from vector
- Conclusion: We're doing well on this benchmark with RVV
- Project reported as a priority for 1H2024
