Fix regression in std::random_device default constructor
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").

fixincludes: vxworks: regs.h: Fix includes in regs.h wrapper
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
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.

diagnostics: add minimum width to left margin for line numbers
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".

[AArch64] Support zero-extended move to FP register
The popcount expansion uses SIMD instructions acting on 64-bit values.
As a result a popcount of a 32-bit integer requires zero-extension before
moving the zero-extended value into an FP register. This patch adds
support for zero-extended int->FP moves to avoid the redundant uxtw.
Similarly, add support for 32-bit zero-extending load->FP register
and 32-bit zero-extending FP->FP and FP->int moves.
Add a missing 'fp' arch attribute to the related 8/16-bit pattern and
fix an incorrect type attribute.
To complete zero-extended load support, add a new alternative to
load_pair_zero_extendsidi2_aarch64 to support LDP into FP registers too.

Make ext allocators support heterogeneous equality comparison
The Allocator requirements include the ability to compare different
specializations of the same allocator class template. This did not work
for __gnu_cxx::new_allocator and other extension allocators. This patch
replaces the equality operators for those allocators with inline friends
that support heterogeneous comparisons. (I'm not changing all ext
allocators because some are bit-rotted already).
Additionally, the equality operators for comparing two std::allocator
objects of the same type are now defined as inline friends. Those
overloads don't need to be declared at namespace scope, because they
aren't specified in the standard (but they're needed in this
implementation to avoid ambiguities caused by the extra overloads
defined for the base allocator type).

with inline friends.

PR libstdc++/87544 limit max_size() to PTRDIFF_MAX / sizeof(T)
The C++17 standard requires the default implementation for
allocator_traits::max_size to return SIZE_MAX / sizeof(value_type).
That causes GCC to warn because the value could be larger than can
sensibly be passed to malloc. This patch changes the new_allocator and
malloc_allocator max_size() members to use PTRDIFF_MAX instead of
SIZE_MAX (and because they define it, the allocator_traits default isn't
used). This also changes vector::max_size to impose a sensible limit
using PTRDIFF_MAX for cases where the value from the allocator or
allocator_traits is not sensible.
