Port .gdbinit to GDB 7.11.1 + Python 2.7.12

* src/.gdbinit (Lisp_Object_Printer.to_string):
Explicitly convert integer val to 'int', so that
older GDBs do not complain about the conversion.
* src/lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]:
Give the struct a tag, so that older GDB pretty-printers have a
tag to hang their hat on.
