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:
`ANSITerminal` flushes after almost every operation. As a result, there is a
lot of flicker in the task bar. Going through `Format` instead reduces the
flicker.
Also erase end-of-lines when outputting logging stuff to the console. This makes sure the output is not garbled with stuff from the task bar.

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:
When `--reanalyze` is passed, mark the summaries of procedures matching
`--procedures-filter` as needing to be analysed before running the analysis.
This allows one to, for instance, re-run the analysis in debug mode on only
some files or procedures. However, this won't work for the Java Buck
integration since the summaries are hidden away in buck-out.

Summary:
Filtering on the SQLite side was done to be more efficient, but these are debug
options so it should be fine for them to be not very optimised.
Filtering on the OCaml side will allow us to re-use these filtering options for
other purposes, such as re-analysing certain procedures only.

Specs do not get invalidated by reactive mode, so we need to delete them all.
Reactive just means that the capture remains valid and the analysis will only
use the freshly captured source files to start the analysis, but all the

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:
The captured/ directory is not guaranteed to exist when the capture was run without debug mode, but the analysis assumes it will be. So, this crashes infer:
```
infer -- clang -c examples/hello.c
infer -g
```
There's no need for `DB.Results_dir.init` to create infer-out and infer-out/specs/ since this is now done in `ResultsDir`.
