Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).

Suggested by Stefan Monnier in
<http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
* alloc.c (widen_to_Lisp_Object): New static function.
(mark_memory): Also mark Lisp_Objects by fetching pointer words
and widening them to Lisp_Objects.  This would work even if
USE_LSB_TAG is defined and wide integers are used, which might
happen in a future version of Emacs.
