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

The constructor `` `Typ`` is never used to build values. Removing type
substitutions from Sil.ml had knock-on effect on Typ.ml etc., resulting in more

Summary:
Previously, the type of `trans_result` contained a list of SIL expressions.
However, most of the time we expect to get exactly one, and getting a different
number is a soft(!) error, usually returning `-1`.
This splits `trans_result` into `control`, which contains the information
needed for temporary computation (hence when we don't necessarily know the
return value yet), and a new version of `trans_result` that includes `control`,
the previous `exps` list but replaced by a single `return` expression instead,
and a couple other values that made sense to move out of `control`. This allows
some flexibility in the frontend compared to enforcing exactly one return
expression always: if they are not known yet we stick to `control` instead (see
eg `compute_controls_to_parent`).
This creates more garbage temporary identifiers, however they do not show up in
the final cfg. Instead, we see that temporary IDs are now often not
consecutive...
The most painful complication is in the treatment of `DeclRefExpr`, which was
actually returning *two* expressions: the method name and the `this` object.
Now the method name is a separate (optional) field in `trans_result`.

Summary:
This simplifies the frontends and backends in most cases. Before this diff,
returning `void` could be modelled either with a `None` return, or a dummy
return variable with type `Tvoid`. Now it's always the latter.

Summary:
This is unused, but the logic for keeping its value up to date was still alive
and kicking.
I don't know that making use of this flag would be easy: we could just use it
in `Ondemand.should_analyze`, but it would be unsound because a procedure might
need to be re-analysed becauese its dependencies have changed. Since there's
not code to deal with that currently I think it's best to remove it and
re-introduce it when we have some idea how to use it.

Summary:
`Sequence` API to walk over free variables in expressions, instead of computing lists with uniqueness constraints that make them have linear complexity for insertion.
Switch to a Set representation when we don't care about the order of elements,
otherwise to a `Hash_queue`:
https://ocaml.janestreet.com/ocaml-core/113.33/doc/core/Std/Hash_queue.mod/S.modt/
Often, we don't even need to compute the sequence of free variables, as we are
just testing membership/emptiness/...

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
