Log:
Fix std::vector's use of temporary objects

	* include/bits/stl_vector.h (emplace(const_iterator, _Args&&...)):
	Define inline. Forward to _M_emplace_aux.
	(insert(const_iterator, value_type&&)): Forward to _M_insert_rval.
	(_M_insert_rval, _M_emplace_aux): Declare new functions.
	(_Temporary_value): New RAII type using allocator to construct/destroy.
	(_S_insert_aux_assign): Remove.
	(_M_insert_aux): Make non-variadic.
	* include/bits/vector.tcc (insert(const_iterator, const value_type&)):
	Use _Temporary_value.
	(emplace(const_iterator, _Args&&...)): Remove definition.
	(_M_insert_rval, _M_emplace_aux): Define.
	(_M_insert_aux): Make non-variadic, stop using _S_insert_aux_assign.
	(_M_fill_insert): Use _Temporary_value.
	* testsuite/23_containers/vector/allocator/construction.cc: New test.
	* testsuite/23_containers/vector/modifiers/insert_vs_emplace.cc:
	Adjust expected results for emplacing an lvalue with reallocation.
	* testsuite/23_containers/vector/check_construct_destroy.cc: Adjust
	expected results to account for construction/destruction of temporary
	using allocator.
