libstdc++: Fix lifetime bugs for non-TLS eh_globals [PR105880]
This ensures that the single-threaded fallback buffer eh_globals is not
destroyed during program termination, using the same immortalization
technique used for error category objects.
Also ensure that init._M_init can still be read after init has been
destroyed, by making it a static data member.
libstdc++-v3/ChangeLog:
PR libstdc++/105880
* libsupc++/eh_globals.cc (eh_globals): Ensure constant init and
prevent destruction during termination.
(__eh_globals_init::_M_init): Replace with static member _S_init.
(__cxxabiv1::__cxa_get_globals_fast): Update.
(__cxxabiv1::__cxa_get_globals): Likewise.
