Summary:
In a future commit `Attributes` will depend on `Procdesc` and that
creates a cycle for the functions concerned with specialising proc
descs, which need `Attributes`.

Summary:
Before storing attributes to disk, we fix their location information if needed.
Ideally we wouldn't be creating bogus attributes but sometimes the frontends
are built in a way that makes it difficult to do otherwise, thus we have to
live with this. However, what's aggravating is that attributes are also saved
in the proc descs of these procedures but in their wrong version. This makes
the two versions (inside the procedures sqlite table and inside the procdesc in
the cfg of the source_files table) agree.

Summary:
Now that we got rid of dummy nodes used non-dummily (biabduction state, reporting), `pname` don't need to be an option anymore.
Let's save a boxing on all nodes.

Summary: No dummy node key, as a consequence the option `--skip-duplicated-types` will have no effect on issues with no node key, i.e. issues reported by non-biabduction non-eradicate checkers.

Summary:
- abstracted the type for a node key
- moved it to its own module with an ugly `compute` to avoid cyclic dependencies...
- renamed `node_id` to `node_id_key` where needed
- moved key computation from `State` to `Procdesc.Node`

Summary: C++17 introduce guaranteed copy elision which omits constructor calls. In ownership analysis, we depended on these constructor calls to acquire ownership. In particular, when a method returns struct, previously, a constructor was used to acquire ownership. In this diff, we acquire ownership of the returned structs directly.

Summary:
This diff:
- translates C++ `catch` blocks
- adds an exceptional control-flow edge from the end of a `try` block to the beginning of a `catch` block
This obviously doesn't reflect the way exceptions actually work, but I think it is better than what we have now. For one thing, we'll see/translate code inside `catch` blocks, which were opaque before. If Clang analyses don't want this behavior, they can simply use `ProcCfg.Normal` (which, up until this diff, behaved identically to `ProcCfg.Exceptional`.
In the future, we can extend `trans_state` to track blocks that might throw an exception, and have each of these blocks transition to `catch` instead.

Summary:
Found the dead code with the script in the next commit, iteratively until no
warnings remained.
Methodology:
1. I kept pretty-printers for values, which can be useful to use from infer's REPL (or
when printf-debugging infer in general)
2. I kept functions that formed some consistent API (but not often, so YMMV), for instance if it looked like `Set.S`, or if it provides utility functions for stuff in development (mostly the procname dispatcher functions)
3. I tried not to lose comments associated with values no longer exported: if the value is commented in the .mli and not the .ml, I moved the comment
4. Some comments needed updating (not claiming I caught all of those)
5. Sometimes I rewrote the comments a bit when I noticed mis-attached comments

Summary:
This will allow most of the checkers, except the bi-abduction, to skip the analysis on the specialized clone of the methods used to handle dynamic dispatch. Doing this, we can run the bi-abduction analysis using:
infer -a checkers --biabduction
without risk of conflicts on the resolution of dynamic dispatch.

Summary:
Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.
