LLVM models ConstantPointerNull as all-zero, but some GPUs (e.g. AMDGPU
and our downstream GPU target) use a non-zero sentinel for null in
private / local address spaces.
SPIR-V is a supported input for our GPU target. This PR preserves a
canonical zero form in the generic AS while allowing later lowering to
substitute the target’s real sentinel.
