libstdc++: Only use std::atomic<tzdb_list::_Node*> if lock free [PR108228]
This fixes linker errors for hppa-hp-hpux11.11 due to an undefined weak
symbol and the use of atomic operations that require libatomic.
The weak symbol can simply be defined, which we already do for darwin.
The std::atomic<_Node*> is only an optimization, so can be avoided for
targets where the underlying atomic ops aren't available without help
from libatomic. The accesses to the std::atomic<_Node*> can be
abstracted behind a new API for getting and setting the cached value,
and then the atomics can be used conditionally.
libstdc++-v3/ChangeLog:
PR libstdc++/108228
PR libstdc++/108235
* config/abi/pre/gnu.ver: Move zoneinfo_dir_override export to
the latest symbol version.
* src/c++20/tzdb.cc (USE_ATOMIC_SHARED_PTR): Define to 0 if
atomic<_Node*> is not always lock free.
(USE_ATOMIC_LIST_HEAD): New macro.
[__hpux__] (__gnu_cxx::zoneinfo_dir_override()): Provide
definition of weak symbol.
(tzdb_list::_Node::_S_head): Rename to _S_head_cache.
(tzdb_list::_Node::_S_list_head): New function for accessing
list head efficiently.
(tzdb_list::_Node::_S_cache_list_head): New function for
updating _S_list_head.

libstdc++: Suppress -Waddress warning in tzdb.cc [PR108228]
For some tarets the weak symbol is always defined, so we get a warning
that its address is never null. The warning isn't useful in this case,
so suppress it.
