Now new features are starting to be added to a C2X draft (in the C2x
branch of the C standard git repository, no public WG14 document yet),
it's time to add -std=c2x and associated options to GCC for use in
enabling C2X features.

This patch adds the expected set of options: -std=c2x, -std=gnu2x,
-Wc11-c2x-compat.  A first C2X feature is added (the only one so far
in the repository that's obviously relevant to GCC): support (as in
C++) for the string constant to be omitted in _Static_assert.  This
feature is duly also supported as an extension in earlier standard
modes (diagnosed with -pedantic, unless -Wno-c11-c2x-compat is given,
or with -Wc11-c2x-compat even in C2X mode).

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

This patch makes references in the manual to C17 reflect it having
been published in July 2018.  (For the reasons it took so long to get
to ballot and publication, see the WG14 convenor's report to the last
SC22 plenary - SC22 N5297 - where it references "A troubling new trend
where ISO CS has begun enforcing undocumented rules that are approved
neither by the TMB nor by the WG 14 editors, leading to a decrease in
the usefulness of standards documents.".)

One target file (config/c6x/t-elf) lists _printf and _gcc_bcmp in
LIB2FUNCS_EXCLUDE, but that does not have any effect, since those are
not filtered away from LIB2FUNCS_ST. Another option is to do as in
config/rl78/t-rl78, which explicitly sets LIB2FUNCS_ST

# Remove __gcc_bcmp from LIB2FUNCS_ST
LIB2FUNCS_ST = _eprintf

but honouring LIB2FUNCS_EXCLUDE also for LIB2FUNCS_ST seems more
natural.

When the default constructor was split out into a separate function (in
r261522) I accidentally  made it call _M_init("mt19937") instead of
_M_init_pretr1("mt19937"). That means it will always throw an exception,
because "mt19937" isn't a valid token accepted by the _M_init function.
Restore the original behaviour by calling _M_init_pretr1("mt19937").

A quick experiment reveals that this hack is needed for C code - simply
removing this hack entirely breaks the build of libstdc++, since
regs.h (more accurately, the cpu-specific header it pulls in) defines
structs in terms of types from vxTypesOld. Those definitions are
properly guarded by #ifndef _ASMLANGUAGE, but the cpu-files do not take
care to include vxTypesOld.h for the types they depend on.

But when using regs.h from some assembly file, the assembler chokes on
the typedefs in vxTypesOld.h. We can fix that by guarding the include of
vxTypesOld by !_ASMLANGUAGE. This should not affect existing C code.

Now, the OS' regs.h contains preprocessor conditionals such as

#if     CPU_FAMILY==I960
...
#endif  /* CPU_FAMILY==I960 */
#if     CPU_FAMILY==MC680X0
...
#endif  /* CPU_FAMILY==MC680X0 */

Without definitions of CPU_FAMILY, I960 etc., these would all be true,
which will not end well. Code using the fix-included regs.h
automatically get vxCpu.h via a chain of includes from vxTypesOld.h, but
we can make regs.h a little more self-contained for both C and asm users
by doing an explicit include of vxCpu.h.

This patch adds a minimum width to the left margin used for printing
line numbers.   I set the default to 6.  Hence rather than:

some-filename:9:1: some message
9 | some source text
  | ^~~~~~~~~~~~~~~~
some-filename:10:1: another message
10 | more source text
   | ^~~~~~~~~~~~~~~~

we now print:

some-filename:9:42: some message
    9 | some source text
      | ^~~~~~~~~~~~~~~~
some-filename:10:42: another message
   10 | more source text
      | ^~~~~~~~~~~~~~~~

This implicitly fixes issues with margins failing to line up due
to different lengths of the number when we haven't read the full
file yet and so don't know the highest possible line number, for
line numbers up to 99999.

Doing so adds some whitespace on the left-hand side, for non-huge
files, at least.  I believe that this makes it easier to see where each
diagnostic starts, by visually breaking things up at the leftmost
column; my hope is to make it easier for the eye to see the different
diagnostics as if they were different "paragraphs".
