Use a simple struct to implement compile time checks for the Lisp_Object type
* configure.in: Rename --enable-use-lisp-union-type to
--enable-check-lisp-object-type and define CHECK_LISP_OBJECT_TYPE
instead of USE_LISP_UNION_TYPE.
* admin/make-emacs: Rename --union-type to --check-lisp-type. Define
CHECK_LISP_OBJECT_TYPE insted of USE_LISP_UNION_TYPE.
* admin/CPP-DEFINES (DEBUG_LISP_OBJECT_TYPE): Renamed from
USE_LISP_UNION_TYPE.
* src/lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
instead of union.
(XLI, XIL): Define.
(XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG): Use
them.
* src/emacs.c (gdb_use_struct): Renamed from gdb_use_union.
* src/.gdbinit: Check gdb_use_struct instead of gdb_use_union.
* src/alloc.c (widen_to_Lisp_Object): Removed.
(mark_memory): Use XIL instead of widen_to_Lisp_Object.
* src/frame.c (delete_frame): Remove outdated comment.
* src/w32fns.c (Fw32_register_hot_key): Use XLI instead of checking
USE_LISP_UNION_TYPE.
(Fw32_unregister_hot_key): Likewise.
(Fw32_toggle_lock_key): Likewise.
* src/w32menu.c (add_menu_item): Likewise.
(w32_menu_display_help): Use XIL instead of checking
USE_LISP_UNION_TYPE.
* src/w32heap.c (allocate_heap): Don't check USE_LISP_UNION_TYPE.
(init_heap): Likewise.
* src/w32term.c (w32_read_socket): Update comment.
