Summary:
Guava subclasses Future in ways that make .get() calls safe from the UI thread.
Treat such methods as skip.

Summary:
Litho uses an idiom as follows. `Component.Builder` has an abstract method `T getThis()` which is supposed to be implemented as `{return this;}`.
I believe the reason it's there is to have covariant return types in subclasses, though this doesn't really matter.
We don't do dynamic dispatch, so instead of summarising `getThis` as having a return ownership of `OwnedIf({ 0 })` we just return `Unowned`.
This is generating many false positives, which are really hard to debug.
Here I'm special-casing any abstract method whose return type is equal to that of it's only argument, to return conditional ownership.

Summary: Exceptional successors were not meant to be created for return nodes, but they were created if try block had a single return statement.

Summary:
Currently, some blocking calls are turning up too many false positives. Adjust severities by fix rate/preexisting numbers.
Also, restrict some calls to exact class, as opposed to superclasses.

Summary:
It adds relational domains to Inferbo: octagon of Apron and polyhedra of Elina.
- Each `Mem` domain value includes one relational value containing relations among *symbols*. The relational values are modified by the `Prune` and `Store` commands.
- Each abstract value includes three *symbols*, which represent integer value, array offset, and array size of an abstract value.
The relational domain is deactivated by default, so this diff should not make any differences in CI.
Use `--bo-relational-domain {oct, poly}` for the activation, though Inferbo with the relational domains does not work at this point because some modifications of Apron and Elina we made has not been applied to their opam repositories yet.

Summary:
The addresses of global variables do not need initialisation to exist and be valid as they are part of the code or data segment of the program. This means that taking the address of a global is not in itself a danger for SIOF. However, dereferencing such an address would be. In order to avoid false positives but avoid being too unsound, only ignore them when the address is taken only to set another global. The general case would require a more complicated abstract domain.

Summary:
- Do not add actuals of a call as unstable.
- Replace access trie with simple set of paths, which is easier to debug/argue correct.
- Fix bug where a prefix path was searched, as opposed to a *proper* prefix.
- Restrict interface to the minimum so that alternative implementations are easier.

Summary: C/C++ code can, in some cases, generate a large number of temporary (Sil) variables. Since we are already not reporting races on these, not recording them gives some perf back.
