Detailed Description

Narrow reduction leaf: the value, the shift applied after widening and the mask applied in the narrow type before widening, clearing the bits the absorbed narrow shls shift out and applying the absorbed narrow and-masks.

Lossless narrow shls contribute their known-zero bits to the mask so matching lanes can form a splat. All-ones mask means nothing was absorbed and no 'and' is needed.
