Implement the proposed solution with `DTGetter` to reuse DominatorTrees from the pass manager. This works fine on the new PM but not on the legacy one. As a workaround, a new DominatorTree is created for every new generated function whenever the Argument Promotion Pass is used through the legacy pass manager.
