If there is no code generated for a source line with just "}", so you are not going to get that line number in debug info (because there is not any llvm instruction). You can access the line number for the last statement/expression in the scope. See http://llvm.org/docs/SourceLevelDebugging.html#ccxx_compile_units for a code snippet on how to get line number from an llvm instruction.
What exactly are you trying to do? Depending on your needs, you may be able to access clang AST nodes to get exact line and column number information for "}" irrespective of debug info.
