  Log Message:
  -----------
  AMDGPU: Remove llvm.amdgcn.addrspacecast.nonnull

The intrinsic is fully replaced by the nonnull flag on addrspacecast,
so remove it.

Old bitcode/IR is autoupgraded, though this is very conservative. This
intrinsic was only inserted by the backend, and hopefully nobody was
directly emitting it.
