For looking at "dead stores" in declarations, we now check to see
if the assigned value is a constant expression, e.g.:
int x = 0;
We then check to see if "x" is ever reassigned later. If so, we don't
emit a warning. This is because programmers frequently use defensive
programming to make sure a variable has a defined value.
