Bug 421041 - NPE in EvalBinding.getBinding

This happens when constructor EvalBinding(IBinding binding, IType type,
IBinding templateDefinition) is called with a null binding. A binding
can be null for example when TypeMarshalBuffer.unmarshalBinding returns
null. Instead of returning null, unmarshalBinding can return a
ProblemBinding and the assumptions that the binding in EvalBinding is
not null can be maintained.
