A title's own libc.prx implements __cxa_thread_atexit and the
destructor pass of exit() through _sceLibcInternalThreadAtexit and
_sceLibcInternalThreadDtors. Its __cxa_finalize calls
_sceLibcInternalForceTlsDestructor.
Destructors are kept per thread and run newest first, including those
registered while they run, as FreeBSD's __cxa_thread_call_dtors does.
A null destructor or one outside every loaded image throws instead of
being skipped. The first registration installs the pass as the
libkernel thread exit hook, so it runs on every guest thread before
the thread can be joined. _sceLibcInternalForceTlsDestructor throws.
