Seems useful to know when we're printing one instruction only, but not when we
print lots of them for readability.

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`.

The constructor `` `Typ`` is never used to build values. Removing type

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:
Using a dummy node here made the whole reporting wrong because it didn't fail getting a `node_key` when reporting issues from checkers not using the biabduction state.
Now that it's fixed, let's fail hard if someone ever tries again.

After some testing, it looks like getting the pdesc via
`Ondemand.get_proc_desc` will also load models' proc descs from their
summaries, so this code should not be needed.

Summary:
`Errlog` will merge similar issues (same severity, name, description) reported at the same location, so let's make sure the locaiton is mandatory.
Issues:
- errors happening in `Ondemand` still use the `State` which makes sense only for biabduction and eradicate
- a case of `NullabilitySuggest` didn't have a location, I did my best to patch it but I'm sure the location could be more precise

Summary:
Before we would convert it to string in `Reporting` and pass it to `Errlog` which would use it only to 'log events'.
I guess the reason is that there was a cyclic dependency between `Errlog` and `clang_method_kind` defined in `ProcAttributes`.
This diff:
- moves it to its own module
- defers the conversion to string

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:
Use `ignore` instead, as this will warn if the argument is an arrow type,
unlike `let _ = ...`. This makes the code more future-proof: if an argument is
added to a function called in `let _ = f x` then the compiler will complain
instead of silently turning a value into a partial evaluation.
Also got rid of particularly irksome `let _ = <stuff returning unit> in` where I could.

We want to kill the cache in `Summary`, and calling `Summary.get` relies on
that cache existing for efficiency. However in this case it's not needed

Summary:
Exposing the in-memory cache seems dangerous. There were only 2 uses anyway:
eradicate and biabduction. I think the biabduction one is safe to remove. The
eradicate one I do not really understand as we return a different summary than
the one we cache... the tests pass though.

Summary:
When we see `pthread_create(..., ..., foo, ...)`, we want to call the function
`foo` to check that its precondition is met. The initial goal was to get rid
of the uncouth call to `Summary.get` when what we really want is to analyse
`foo` instead of just betting on the fact that it has been analysed already.
Besides switching to `Ondemand.analyze_proc_name`, this also changes the
matching of the function pointer in the arguments of `pthread_create()` to
detect the common case of a constant function name. I also added tests.
