(INTMASK, MOST_POSITIVE_FIXNUM): Use it.
(LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P): Simplify
now that USE_LSB_TAG is always defined.
(TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.
(make_number) [!USE_LSB_TAG]: Use INTMASK; that's simpler.

* src/s/usg5-4-common.h (USG5_4): No longer define; unused.

* admin/CPP-DEFINES, src/s/template.h: Related edits.

--enable-check-lisp-object-type and define CHECK_LISP_OBJECT_TYPE

CHECK_LISP_OBJECT_TYPE insted of USE_LISP_UNION_TYPE.

This was added in 2012-01 in response to http://debbugs.gnu.org/10552 .
However, this issue had already been fixed in the trunk two years
earlier, by removing POSIX_SIGNALS altogether. Ref:

http://lists.gnu.org/archive/html/emacs-devel/2010-04/msg00002.html

* alloc.c (make_number) [!defined make_number]:
Remove, as lisp.h always defines this now.
(mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.

-DUSE_LSB_TAG=0, to override the automatically-selected default.
USE_LSB_TAG now is always defined to be either 0 or 1.
All uses changed.
(union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
code works fine either way, and efficiency is not a concern here,
as the union type is for debugging, not for production.
(LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
Use an inline function on all platforms when using the union type,
since this is simpler and 'static inline' can be used portably
within Emacs now.

(XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
(XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
