According to the [spec](https://github.com/intel/llvm/blob/sycl/sycl/doc/design/spirv-extensions/SPV_INTEL_function_pointers.asciidoc), it is illegal to addrspacecast to the generic AS, so use the function pointer AS for null constants. "It is illegal to use Function Pointer as 'Pointer' argument of OpPtrCastToGeneric." This was found when compiling the OpenMP Device RTL for SPIR-V. Signed-off-by: Nick Sarnie <nick.sarnie@intel.com>
