cb4453dc - [SelectionDAG] Prevent combination on inconsistent type in `combineCarryDiamond` (#84888)

[SelectionDAG] Prevent combination on inconsistent type in `combineCarryDiamond` (#84888) Fixes #84831 When matching carry pattern with `getAsCarry`, it may produce different type of carryout. This patch checks such case and does early exit. I'm new to DAG, any suggestion is appreciated.
