Konstantin Belousov b7c7684ae2 Export __cxa_thread_atexit_impl as an alias for __cxa_thread_atexit. 
libstdc++ before gcc r244057 expected that libc provided
__cxa_thread_atexit_impl, and libstdc++ implemented
__cxa_thread_atexit, by forwarding the calls to _impl.  Mentioned gcc
revision checks for __cxa_thread_atexit in libc and does not provide
the symbol from libstdc++ if found.

This change helps older gcc, in particular, all released versions
which implement thread_local, by consolidating the implementation into
libc.  For that versions, if configured with the current libc, the
__cxa_thread_atexit is exported from libstdc++ as a trivial wrapper
around libc::__cxa_thread_atexit_impl.

The __cxa_thread_atexit implementation is put into separate source
file to allow for static linking with older libstdc++.a.
