About
The bwaves benchmark has some vector opportunities. x86_64 is seeing roughly a 10% improvement due to vectorization, but aarch64 is getting no measurable improvement. This may point to a problem with VLA style vectorization.

Updates
- Seeing a roughly 5% improvement in dynamic instruction counts
- x86_64 sees a 10% runtime improvement from vectorization
- aarch64 sees no improvement from vectorization
- Suspect there's a problem with VLA style vectorization. Happy we're seeing a 5% count improvement, but not enough to get us on-par with x86
- Project reported as a priority for 1H2024
