Fix an issue with defining actual DWARF address space for module scope globals. Previously it was always `ADDR_global_space`. Also, this patch introduces CUDA-specific DWARF codes for address space specification in correspondence with: https://docs.nvidia.com/cuda/ptx-writers-guide-to-interoperability/index.html#cuda-specific-dwarf-definitions Previously hardcoded constant values are replaced with enum values.
