re PR libstdc++/58338 (Add noexcept to functions with a narrow contract) 

2013-09-17  Marc Glisse  <marc.glisse@inria.fr>

	PR libstdc++/58338
	* include/bits/stl_vector.h (vector::vector(),
	vector::vector(const allocator_type&)): Merge.
	(_Vector_impl::_Vector_impl(_Tp_alloc_type const&),
	_Vector_impl::_Vector_impl(_Tp_alloc_type&&),
	_Vector_impl::_M_swap_data,
	_Vector_base::_Vector_base(const allocator_type&),
	_Vector_base::_Vector_base(allocator_type&&),
	_Vector_base::_Vector_base(_Vector_base&&), _Vector_base::~_Vector_base,
	vector::vector(const allocator_type&), vector::operator[],
	vector::operator[] const, vector::front, vector::front const,
	vector::back, vector::back const, vector::pop_back,
	vector::_M_erase_at_end): Mark as noexcept.
	* include/debug/vector (vector::vector(const _Allocator&),
	vector::operator[], vector::operator[] const, vector::front,
	vector::front const, vector::back, vector::back const, vector::pop_back,
	_M_requires_reallocation, _M_update_guaranteed_capacity,
	_M_invalidate_after_nth): Mark as noexcept.
	* include/profile/vector (vector::vector(const _Allocator&),
	vector::operator[], vector::operator[] const, vector::front,
	vector::front const, vector::back, vector::back const): Mark as
	noexcept.
	(vector::vector(vector&&, const _Allocator&)): Remove wrong noexcept.
	* testsuite/23_containers/vector/requirements/dr438/assign_neg.cc:
	Adjust line number.
	* testsuite/23_containers/vector/requirements/dr438/
