Why do we end up with that IR? It looks like one lowering was configured with 32-bit index and another with 64-bit index. We should rather fix the root cause -- using incompatible configurations -- than have such local fixes that hide the misconfiguration. Furthermore, this fix will become insufficient the moment the order of operations is switched, and one would need to truncate (which would be definitely undesirable as a silent fixup).
