Summary: If the LLVM module shows that it has debug info, but the file is actually empty and the real debug info is not emitted, the ptxas tool emits error 'Debug information not found in presence of .target debug'. We need at leas one empty debug section to silence this message. Section `.debug_loc` is not emitted for PTX and we can emit empty `.debug_loc` section if `debug` option was emitted.
