PR libstdc++/88881 fix filesystem::symlink_status for Windows

The fix for PR 88881 only added a workaround to filesystem::status, but
filesystem::symlink_status is also affected by the _wstat bug and needs
the same workaround.

The recent change to optimize path::parent_path() means that the
workaround can be simplified to just use parent_path().

PR libstdc++/85494 use rdseed and rand_s in std::random_device

Add support for additional sources of randomness to std::random_device,
to allow using RDSEED for Intel CPUs and rand_s for Windows. When
supported these can be selected using the tokens "rdseed" and "rand_s".
For *-w64-mingw32 targets the "default" token will now use rand_s, and
for other i?86-*-* and x86_64-*-* targets it will try to use "rdseed"
first, then "rdrand", and finally "/dev/urandom".

To simplify the declaration of std::random_device in <bits/random.h> the
constructors now unconditionally call _M_init instead of _M_init_pretr1,
and the function call operator now unconditionally calls _M_getval. The
library code now decides whether _M_init and _M_getval should use a real
source of randomness or the mt19937 engine.

Existing code compiled against old libstdc++ headers will still call
_M_init_pretr1 and _M_getval_pretr1, but those functions now forward to
_M_init and _M_getval if a real source of randomness is available. This
means existing code compiled for mingw-w64 will start to use rand_s just
by linking to a new libstdc++.dll.

Current vectoriser doesn't support masked loads for SLP.

Current vectoriser doesn't support masked loads for SLP. We should add that, to
allow things like:

void
f (int *restrict x, int *restrict y, int *restrict z, int n)
{
  for (int i = 0; i < n; i += 2)

[aarch64] Change two function declaration types

Commit r271514 missed changing the type of two functions in
aarch64-protos.h.  The function definitions had been updated to use
uint64_t while the function declarations had been missed.
They were missed since I only tested the patch on aarch64 where
`unsigned long` is the same as `uint64_t`.

This patch updates these declarations in aarch64-protos.h.

Tested by building an aarch64 cross-compiler on arm-none-linux-gnu (so
that `unsigned long` and `uint64_t` are different and would give error
messages), and bootstrapping on aarch64-none-linux-gnu.
Also manually tested command line options to see that
-march=armv8-a+typo prints out the expected flags while using the new
feature flags does not complain about missing flags.
