Thank you all for your comments.
So let me sum up the options from the various comments here:
A - Keep this change in the SLP vectorizer. This requires emitting GPR operations instead of vector operations, and updating the cost model.
B - Do this in DAG, inside or near to LoadCombine.
I'll explore both solutions and create a patch with (B) so that we can compare.
