Add proper unwind information for x86_64 _fini

It is impossible to reliably unwind the stack above _fini() on x86_64 since no
unwind information is provided for it and it modifies a stack register. This
matters for gdb backtracing - if a process crashes within a destructor, it can
frequently be essential to look at why the program began terminating in the
first place.
