Howard Hinnant aab2305454 Seciton 24.2.2 of the C++ standard, [iterator.iterators], Table 106
requires that the return type of *r for all iterators r be reference,
where reference is defined in [iterator.requirements.general]/p11 as
iterator_traits<X>::reference, and X is the type of r.

But in CFG.h, the dereference operator of PredIterator and SuccIterator
return pointer, not reference.

Furthermore the nested type reference is value_type&, which is not the
type returned from operator*().

This patch simply makes the iterator::reference type value_type*, which
is what the operator*() returns, and then re-lables the return type as
reference.

From a functionality point of view, the only difference is that the
nested reference type is now value_type* instead of value_type&.
