[PATCH] D44557: [analyzer] CStringChecker.cpp - Code refactoring on bug report.

When improving the modeling `evalMemset()`, some scenes need to emit report of `NotNullTerm`. In this case, 
there are three places in `CStringChecker.cpp` that have the same code about `NotNullTerm` report. In 
addition, `CStringChecker.cpp` already has `emitOverlapBug()`, so I think it needs code refactoring.

Thanks in advance for the code review!
