Looks like this was fixed while I was busy with other things -
https://github.com/llvm/llvm-project/pull/140213 changed this code to drop the
invalid width usage. I'll update this PR to just add a test for the ptrtoint
case.

Thanks for the review, I'll update this to use a new baseline test that does
not depend on the new ptrtoaddr.

The current behaviour is definitely buggy since we lower G_PTRTOINT as a COPY
node, but assume that it zeroes the upper bits for ptr addrspace(8). I think
this patch is sufficient to prevent that issue.
