Summary:
The frontend was hackily adding protocols as superclasses in the tenv, with the implicit encoding that the first element in the list was the actual superclass. This was clearly very fragile.
Protocols are not used in the backend at the moment, so for now we will remove them from the list of superclasses to have more consistency in the tenv.

Summary:
As title
Model `NSString` as `JavaString`.
Since `NSArray` does not contain information about its type of element, we do not use associate string with collection as in Java and C++. In Java, String model is implemented using java collection, and for C++, string model is implemented using vector.
So instead, we use existing `JavaString` model.

Summary:
After merging https://github.com/facebook/facebook-clang-plugins/pull/20, we can now use Actions here to download a facebook-clang custom clang Release here and use it to build C Analyzers during CI, as well as Java Analyzers.
1. had to change `matrix.os: macos-latest` to `matrix.os: macOS-latest`. I guess that's what I typed for the fb clang build, and `curl`ing a Release asset is case-sensitive.
2. Add `jq` to installed packages on mac - we need it for parsing GitHub's API responses
3. Add the logic for fetching a release asset (we currently only look for the `"latest"` release) and downloading the properly-named clang based on OS. Then unpack it and update the `opam` files so we build with clang.
Note: I would have used this Action: https://github.com/dsaltares/fetch-gh-release-asset/ for fetching a Release asset, but unfortunately it seems to be in a fairly new state and it's a Docker Action, which means it doesn't support macOS. The logic in the fetch clang step is roughly based off of this action's logic.

Summary:
In order to allow implementations of the single Fol interface using
multiple backend first-order logic solvers, add explicit definitions
of terms and formulas in the Fol module, and implement Context in
terms of them.
The Fol interface supports freely mixing Terms and Formulas, in
particular there is `Term.ite : cnd:Formula.t -> thn:Term.t ->
els:Term.t -> Term.t` which allows Formulas to appear in Terms. The
Fol implementation performs enough normalization to enable using an
internal representation of terms that is strictly partitioned into
"theory terms" and "formulas", which are stratified below "conditional
terms" and then below "general terms". This partitioning and
stratification enables using backend solvers that do not support
mixing formulas in terms.

Summary:
The eventual aim is for the conversion of Llair to Fol to be external
to Fol. Fol should not need to depend on Llair, nor vice versa. This
is not yet possible, but a step forward is to move the conversion
functions into separate modules outside the core Fol modules.
