[clang][SPIRV] Don't addrspacecast nullptr for function pointer types (#167379) ...

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.
