Summary:
This diff fixes a bug in the translation of an empty for-loop. When both initialization and
incrementation statements did not introduce a new node, the frontend generated an incorrect results
where the for-loop was unreachable from the entry node.

Summary:
This diff adds a constant to the set of widening thresholds if the
constant is compared to an abstract value in condition expressions.
Each abstract value has its own set of thresholds.

Summary:
This diff preserves values of offset and index separately, rather than
one value of their addition, because premature addition results in
imprecise FPs by the limited expressiveness of the domain.

Summary:
Fix the logic for computing duplicate symbols. It was broken at some point and some duplicate symbols creeped into our tests. Fix these, and add a test to avoid duplicate symbols detection to regress again.
Also, this removes one use of `Cfg.load`, on the way to removing file-wide CFGs from the database.
