Blend and improved mask support

- Mask loading from boolean array is complete for all combinations
- Blending is supported for all possible types and sizes (except 512)
- Masked loads, stores, and several binary operations are now supported via
use of blend
- Fix for a memory ordering issue
- Fix for rebracketing intrinsification which requires shape retention
