Summary:
It suppresses intended integer overflows that generate hash values or random numbers. For judging that the intention of integer overflow, it applies a heuristics: checking if traces of issues include a whitelisted words, e.g., "rand" or "seed".
While we would be able to suppress all integer overflows of unsigned integers since they have defined behaviors, we don't want to miss unintended integer overflows, e.g., that on unsigned index value.
