[libFuzzer] Handle unstable edges by disregarding unstable edges
Summary: Added a new mode within flag -handle_unstable for new unstable handling algorithm that does the following: When an edge is shown as unstable, copy to UnstableCounters the value 0. During ApplyUnstableCounters we copy back the value 0 to ModuleInline8bitCounters if the edge was unstable. This way we would be ignoring completely features that were collected through non-determinism. Unstable hits would be counted as if it never hit.
