Define TS 18661-1 CR_DECIMAL_DIG in <float.h>.

TS 18661-1 defines a macro CR_DECIMAL_DIG in <float.h>, for the number
of decimal digits for which conversions between decimal character
strings and (IEEE) binary formats, in both directions, are correctly
rounded.  This patch implements support for this macro in GCC's
<float.h>.

The definition __UINTMAX_MAX__ is the right one for GCC's conversions
of floating constants, since I made those use MPFR to make them
correctly rounding.  The macro also covers standard library functions
such as strtod and printf.  The definition is also correct for current
glibc.  If any targets' libcs support correct rounding in a way that
conforms to TS 18661-1 with a smaller value of CR_DECIMAL_DIG, making
<float.h> reflect that could not be done in isolation without changes
to the interpretation of floating constants as well, since a smaller
CR_DECIMAL_DIG requires double rounding of floating constants (first
to CR_DECIMAL_DIG decimal digits, then to the desired binary format).

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

* ginclude/float.h [__STDC_WANT_IEC_60559_BFP_EXT__]

Make max_align_t respect _Float128.

The _FloatN, _FloatNx, _DecimalN and _DecimalNx types are specified in
such a way that they are basic types, meaning that max_align_t must be
at least as aligned as those types.

On 32-bit x86, max_align_t is currently 8-byte aligned, but
_Decimal128 and _Float128 are 16-byte aligned, so the alignment of
max_align_t needs to increase to meet the standard requirements for
these types.

This patch implements such an increase.  Because max_align_t needs to
be usable for C++ as well as for C, <stddef.h> can't actually refer to
_Float128, but needs to use __float128 (or some other notation for the
type) instead.  And since __float128 is architecture-specific, there
isn't a preprocessor conditional that means "__float128 is available"
(whereas one could test __FLT128_MANT_DIG__ to see if _Float128 is
available; __SIZEOF_FLOAT128__ is available on x86 only).  But I
believe the only case that actually has an alignment problem here is
32-bit x86, and <stddef.h> already has lots of conditional specific to
particular architectures or OSes, so this patch uses a conditional on
__i386__; that also is the minimal change that ensures neither size
nor alignment of max_align_t is changed in any case other than where
it is necessary.  If any other architectures turn out to have such an
issue, it will show up as failures of one of the testcases added by
this patch.

Such an increase is of course an ABI change, but a reasonably safe
one, in that max_align_t doesn't tend to appear in library interfaces
(rather, it's something to use when writing allocators and similar
code; most matches found on codesearch.debian.net look like copies of
the gnulib stddef.h module rather than anything actually using
max_align_t at all).

max_align_t_align has a corresponding change (adding _Float128 to the
types considered).

(I think glibc malloc alignment should also increase to 16-byte on
32-bit x86 so it works for allocating objects of these types, which is
now straightforward given the fix made for 32-bit powerpc.)

Bootstrapped with no regressions on x86_64-pc-linux-gnu, and
spot-tested with -m32 that the new float128-align.c test now compiles
where previously it didn't.
