## Detailed Description

This iterator uses masks to guard out-of-bounds accesses and visits the last "residue" tile first, with the objective of minimizing predicate mask updates during steady-state operation.

A precomputed "Params" object minimizes the amount of state that must be stored in registers, and integer addition is used to advance the pointer through memory.
