Define __HAVE_ATOMIC_CAS_64_UP and provide __sync_val_compare_and_swap_8

The new santizer code in gcc12 needs this.

	common/lib/libc/arch/sh3/atomic/Makefile.inc: revision 1.9

libc: Define __atomic_is_lock_free.

Limited to architectures where it is actually needed by gcc for any
calls to stdatomic.h atomic_is_lock_free for now.

We should also add it to other architectures too, along with lockful
atomic r/m/w operations for sizes that can't be handled natively, but
that's a lot more work.  It is also necessary for -fno-inline-atomics
but we're missing a lot of other symbols for that too, to be fixed.

For now, this should enable the OpenSSL build to complete on these
architectures again after I reverted a local change.

Add missing atomic_and_{8,16}_nv_cas.c for __sync_and_and_fetch_{1,2}.
XXX why is not only atomic_and_* symmetric unlike the others?

Add __sync_val_compare_and_swap_{1,2} aliases for _atomic_cas_{8,16}
--
Provide __atomic_compare_exchange_N (as needed for the C11 2011 <atomic>
ops) via the corresponding CAS.
--
Hook __atomic_compare_exchange_N into vax libc.
--
Provide __sync_and_and_fetch_2 and __sync_and_and_fetch_1 for pre-ARMv6,
they are needed for the C++ 2011 <atomic> stuff.
--
Add C++ 2011 <atomic> support functions.
--
Move the and_{16,8}_nv sources into the right (libc only) block.
--
Provide <atomic> C++ 2011 support functions for mips and sh3.
--
Provide C++ 2011 <atomic> support functions for hppa and arm.
--
Provide prototypes to fix build with clang.

Provide C++ 2011 <atomic> support functions for hppa and arm.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Add the missing __sync_* ops to libc

Another layout change

Layout changes - no functional change.

Provide _atomic_cas_8_up and _atomic_cas_16_up functions

Tweak layout - no functional change.

The .if conditional crosses a line boundary, so add a backslash.

This fixes the kernel build for hppa.

allow inclusion of atomic ops in librump

Allow atomic ops to be built as part of libpthread.

Sync with wrstuden-revivesa-base-2.

Provide assembly _atomic_cas_up() as the compiler cannot be trusted to
generate fully restartable code sequences.

sync with HEAD

Only build atomic ops for libkern/libc.

Enable the atomic ops in userspace.
