* include/bits/forward_list.h (forward_list<>::erase_after):
Change signature per N2988, return void; simplify.
(_Fwd_list_base<>::_M_erase_after): Likewise return void.
(forward_list<>::~forward_list): Do not call _M_erase_after
unnecessarily, the base class destructor already does it.
(forward_list<>::splice_after(const_iterator position,
forward_list&&, const_iterator i): Check position != i and
position != ++i.
* include/bits/forward_list.tcc (_Fwd_list_base<>::
_M_erase_after(typename _Node_base::_Pointer): Simplify.
(_Fwd_list_base<>::_M_erase_after(typename _Node_base::_Pointer,
typename _Node_base::_Pointer): Fix (remove the correct range
of element) and simplify (update __pos->_M_next at the end).
