Not a fan of this I'm afraid. I used to have address space support in
the nvptx backend, but the middle-end was too broken for it to work, so
I made nvptx deal with all the address space complications internally.
Is there a reason why this approach can't work for what you want to do?
(Also, where are you using this?)
