I guess my next question would be how the SPIR-V situation differs from the DXIL situation. For DXIL you have already implemented code to "guess" pointer types insofar as they are relevant -- does SPIR-V need something more than that? Clang is only permitted to encode pointer type information is if that pointer type has some kind of direct semantic meaning -- say, if the pointer element type affects the call ABI in some way. If it does not have direct semantic meaning, then deriving the pointer type based on usage (as DXIL does) and using that for emission would be right approach.
