Why don't we emit nonnull if the address space is something other than
zero?

>From the explanation in the commit message I would've expected logic
like:

1. If we have a complete type, add the dereferenceable attribute
2. If we don't have a complete type or if we are not in addrspace(0),
   add the nonnull attribute

It could be I didn't understand the explanation though.
