alignasof: new module
This splits off support for the C23 keywords alignas and alignof,
from the now-deprecated stdalign module. The latter now merely
provides C11 support.
* MODULES.html.sh, NEWS, doc/gnulib.texi:
* doc/posix-headers/stdalign.texi: Document the change.
* lib/stdalign.in.h: Remove most of the definitions (which are now
supplied by the alignasof module), leaving only
__alignas_is_defined and __alignof_is_defined.
* modules/alignasof, modules/alignasof-tests: New files.
* m4/stdalign.m4 (gl_ALIGNASOF): New macro, with
most of the contents of the old gl_STDALIGN_H.
Do not define __alignas_is_defined or __alignof_is_defined.
(gl_STDALIGN_H): Rely on gl_ALIGNASOF for most of the work.
* modules/alignalloc, modules/alignof, modules/argp:
* modules/crypto/md4-buffer, modules/crypto/md5-buffer:
* modules/crypto/sha1-buffer, modules/crypto/sha256-buffer:
* modules/crypto/sha512-buffer, modules/crypto/sm3-buffer:
* modules/fts, modules/rawmemchr, modules/relocatable-prog-wrapper:
* modules/stddef-tests, modules/sys_socket:
Depend on alignasof, not stdalign.
* modules/stdalign: Deprecate. Depend on alignasof.
* modules/stdalign-tests: Move most contents to the new module
alignasof-tests, and depend on that.

stdalign: alignas and alignof are C23 keywords
* m4/stdalign.m4 (gl_STDALIGN_H): Check also whether
alignas and alignof are keywords and so don’t need stdalign.h,
and define HAVE_C_ALIGNASOF if so.
If not, arrange for config.h to #define alignas and alignof
by including <stdalign.h>.
* modules/stdalign: No need to include <stdalign.h>.
* tests/test-stdalign.c: Do not include stdalign.h.

stdalign-tests: port to C23
* tests/test-stdalign.c: Do not test __alignas_is_defined,
_Alignof, or _Alignas as they are obsolescent.
Do not use __alignas_is_defined in C23 or later (or C++11 or later),
as it’s removed in C23.

stdalign: correct mistake in alignof doc
Problem reported by Joseph Myers in:
https://gcc.gnu.org/ml/gcc-patches/2016-09/msg00340.html
* doc/posix-headers/stdalign.texi: Do not imply that C11 prohibits
alignof(S) where S is a structure containing a flexible array
member. The Gnulib substitute does not support this, but C11 does.

stdalign: port better to MSVC and to Sun C 5.11
I think these problems were reported by Bruno Haible, in email
that I've unfortunately misplaced.
* doc/posix-headers/stdalign.texi (stdalign.h): Document more
shortcomings of MSVC and of Sun C 5.11.
* lib/stdalign.in.h (_Alignas): Omit bogus extra parenthesis
around __declspec arg.
* modules/stdalign-tests (Files): Add tests/macros.h.
* tests/test-stdalign.c: Do not include <stdlib.h>; no longer needed.
Include macros.h, for ASSERT.
(DECLARE_ALIGNED): Remove.
(TEST_ALIGNMENT): Define to 16 if alignment is supported (more likely
to catch bug), and to 1 if not (simplifies the rest of the code).
(CHECK_STATIC): Always declare the alignment test vars; that's simpler.
(CHECK_AUTO): Remove.
(CHECK_ALIGNED): Check only the alignment of the static vars,
since auto var alignment isn't supported by Sun C 5.11.
(CHECK_TYPES): Remove. All uses replaced by inline code, so that
ASSERT failures are easier to diagnose.
