Summary: We do not want to export unnecessary information from clang plugin, hence, the solution to this false positive would be to annotate with `__unused__` attribute.

Summary:
This will allow to get the numerical results for Cost, Hoisting, Purity without the Inferbo issues.
For now, I still forced Inferbo issues for Cost and Purity to avoid lots of changes in tests, that will go away soon.

Summary:
This diff extends the abstract domain to keep binary conditions on
prunings, so Inferbo can suppress more proof obligations (i.e., false
positives) that are known to be unreachable according to the binary
conditions.

Summary:
In ObjC there are no access modifiers. The strongest alternative is to put methods in the implementation but omit them from the interface declaration.
Put exported ObjC methods in their own field in the class structure and use that in RacerD to decide whether to report on the method.

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.
