> 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.
