Simon Marchi 774d21c10b gdbsupport: add missing increment/decrement operators to reference_to_pointer_iterator 
Using the following patch, I would get this build failure:

          |           ^~~~~

This points out that while intrusive_list_iterator has an operator--,
the reference_to_pointer_iterator wrapper does not.  I'm not to sure why
the compiler chooses the overload of __advance that accepts a
_BidirectionalIterator, given that reference_to_pointer_iterator can't
be decremented, but adding those operators seems like the right thing to
do in any case, for completeness.
