Alexey Bataev 1a9e05d7da [DEBUG_INFO][NVPTX] Generate correct data about variable address class.
Summary:
Added ability to generate correct debug info data about the variable
address class. Currently, for all the locals and globals the default
values are used, ADDR_local_space(6) for locals and ADDR_global_space(5)
for globals. The values are taken from the table in
  https://docs.nvidia.com/cuda/archive/10.0/ptx-writers-guide-to-interoperability/index.html#cuda-specific-dwarf.
  We need to emit correct data for address classes of, at least, shared
  and constant globals. Currently, all these variables are treated by
  the cuda-gdb debugger as the variables in the global address space
  and, thus, it require manual data type casting.
