C++ (checker): For iterators, warn of the use of "iterator++" instead
of "++iterator" when when the value returned by operator++(int) is
ignored.

+We want to keep more source range information in Declarator to help
+produce better diagnostics. Declarator::getSourceRange() should be
+implemented to give a range for the whole declarator with all of its
+specifiers, and DeclaratorChunk::ParamInfo should also have a source
+range covering the whole parameter, so that an error message like this:
+
+overloaded-operator-decl.cpp:37:23: error: parameter of overloaded post-increment operator must have type 'int' (not 'float')
+X operator++(X&, const float& f);
+ ^
+can be turned into something like this:
+
+overloaded-operator-decl.cpp:37:23: error: parameter of overloaded post-increment operator must have type 'int' (not 'float')
+X operator++(X&, const float& f);
+ ^ ~~~~~~~~~~~~~~
