Summary: According to https://docs.nvidia.com/cuda/archive/10.0/ptx-writers-guide-to-interoperability/index.html#cuda-specific-dwarf, the compiler should emit the DW_AT_address_class attribute for all variable and parameter. It means, that DW_AT_address_class attribute should be used in the non-standard way to support compatibility with the cuda-gdb debugger. Clang is able to generate the information about the variable address class. This information is emitted as the expression sequence `DW_OP_constu <DWARF Address Space> DW_OP_swap DW_OP_xderef`. The patch tries to find all such expressions and transform them into `DW_AT_address_class <DWARF Address Space>` if target is NVPTX and the debugger is gdb. If the expression is not found, then default values are used. For the local variables <DWARF Address Space> is set to ADDR_local_space(6), for the globals <DWARF Address Space> is set to ADDR_global_space(5). The values are taken from the table in the same section 5.2. CUDA-Specific DWARF Definitions.
