The main change in this patch is to add a 'IsDecl' field to DIModule so that when IsDecl is set to true, the debug info entry generated for the module would be marked as a declaration. That way, the debugger (GDB at least) would look up the definition of the module in the gloabl scope.

      

Please see the comments in llvm/test/DebugInfo/X86/dimodule.ll for what the debug info entries would look like.
