> This PR improves the performance of vector operations that accept masks on architectures that support masking in hardware, specifically Intel AVX512 and ARM SVE.
>
> On architectures that do not support masking in hardware the same technique as before is applied to most operations, specifically composition using blend.
>
> Masked loads/stores are a special form of masked operation that require additional care to ensure out-of-bounds access throw exceptions. The range checking has not been fully optimized and will require further work.
>
> No API enhancements were required and only a few additional tests were needed.
