Adam Balogh 0a7592b5e2 [Analyzer] Mark SymbolData parts of iterator position as live in program state maps ...

Marking a symbolic expression as live is non-recursive. In our checkers we
either use conjured symbols or conjured symbols plus/minus integers to
represent abstract position of iterators, so in this latter case we also
must mark the `SymbolData` part of these symbolic expressions as live to
prevent them from getting reaped.
