<summary>Changes</summary>
We were only folding cases which remained extloads, but DAG.getExtLoad can also handle the cases where don't need to extend at all (we just can't do truncloads)
reduceLoadWidth can handle this for scalar loads, but not for vectors.
There's some major AMDGPU codegen changes (especially kernel-args.ll), I don't know if this is OK, or whether it was relying on any particular behavior.
Noticed while triaging D152928
