Summary:
Created unstable_handle flag that takes 1 or 2, depending on the handling type.
Modified RunOne to accommodate the following heuristic:
Use the first CollectFeatures to count how many features there are.
If no new features, CollectFeatures like before.
If there is new feature, we run CB 2 more times,
Check which edges are unstable per input and we store the least amount of hit counts for each edge.
Apply these hit counts back to inline8bitcounters so that CollectFeatures can work as intended.
Modified UnstableCounters to 8int_t and created a bitset UnstableSet to tell which edges are unstable.

Summary:
Created IterateInline8bitCounters, a single template for visiting Inline8bitCounters (nested for loop)
Made InitializeUnstableCounters and UpdateUnstableCounters both send a lambda to IterateInline8bitCounters.

This is a fix for bug 37047.
https://bugs.llvm.org/show_bug.cgi?id=37047
Implemented by basically reversing the logic. Previously all strings
were considered, with some operations excluded. Now strings are excluded
by default, and only strings during the CB considered.

unstable edges.
Summary:
Created a -print_unstable_stats flag.
When -print_unstable_stats=1, we run it 2 more times on interesting inputs poisoning unstable edges in an array.
On program termination, we run PrintUnstableStats() which will print a line with a stability percentage like AFL does.

Summary: This is a minor cosmetic change. When function/path exceed ~1000 characters, the output is truncated before the line-break. I noticed this for NEW_FUNC.
