Limit operations on vector::pointer to NullablePointer requirements.

Browse Source 
* include/bits/stl_vector.h (_Vector_base::_Vector_impl,
	_Vector_base::_M_allocate): NullablePointer requirements do not
	include initialization from literal zero, use value-initialization.
	* include/bits/vector.tcc (vector::_M_insert_aux,
	vector::_M_explace_back_aux): Likewise for assignment.
