@llvm-beanz  I think I misunderstood what you were asking. We aren't implementing the TTI for all of `VectorUtils`. We don't have tests for target intrinsics that are vectorizable. Maybe one day it makes sense to add them for SPIRV?  But for DirectX keeping these changes in the Scalairzer is our path forward. It looks like @inbelic  did update all the Scalairzer uses.
