Thanks for reviewing this patch, @rovka and @sdesmalen!

+             Kind == PtrToElt || Kind == VecElementArgument ||
+             Kind == Subdivide2Argument || Kind == Subdivide4Argument);
       return Argument_Info >> 3;

I think it's probably best not to include VecOfAnyPtrsToElt here as it was removed from the assert when the functions //getOverloadArgNumber// and //getRefArgNumber// below were added (these should be used instead of getArgumentNumber in this case).


================
Comment at: lib/IR/Function.cpp:1312
+    case IITDescriptor::Subdivide4Argument: {
+      // This may only be used when referring to a previous vector argument.
+      if (D.getArgumentNumber() >= ArgTys.size())
----------------

This code is now shared, as is the code to handle Subdivide2Argument & Subdivide4Argument in Function.cpp above.
