> We already have the arith-int-narrowing pass, but it mostly only doing local analysis, while IntegerRangeAnalysis analyses entire program. They ideally should be unified, but it's a task for the future.

AFAIK, `arith-int-narrowing` doesn't have any use(r)s and could be dropped. I think it would be better to replace it with the new implementation in this PR.
