LGTM. You can adopt my suggestion while committing.



================
Comment at: llvm/lib/Target/AVR/AVRTargetMachine.h:57
+    // pointers.
+    return getPointerSize(SrcAs) == getPointerSize(DestAs);
+  }
----------------
it would be better to also check the range, something like

```
   return SrcAs < AVR::NumAddrSpaces && DestAs < AVR::NumAddrSpaces &&
          getPointerSize(SrcAs) == getPointerSize(DestAs);
```
