[PATCH] D44606: [analyzer] Fix the crash in `IteratorChecker.cpp` when `SymbolConjured` has a null Stmt.

[Henry Wong via Phabricator via cfe-commits]

MTC added a comment.

> One small nit for future debugging people: Could you insert a comment line in the test case where you explain what is this all about? E.g what you just have written in the description: "invalidateRegions() will construct the SymbolConjured with null Stmt" or something like this.

Thank you for pointing this out, and I'll add the comment.
