[GISel] Keep non-negative info in SUB(CTLZ) (#189314) ...

Implement non-negative value tracking for SUB-CTLZ chains in GlobalISel,
matching the behavior previously added to SelectionDAG.

Additionally, refactor the SelectionDAG implementation from the previous
patch to improve performance and code density.
