LOG: [Analyzer][NFC] Separate white-box tests for iterator modelling from iterator checker tests

The recently committed debug.IteratorDebugging checker enables
standalone white-box testing of the modelling of containers and
iterators. For the three checkers based on iterator modelling only
simple tests are needed.
