Summary:
Since floats of any width are interpreted the same (as exact rationals
where possible and uninterpreted constants otherwise), this does not
introduce additional infidelity.

Summary:
Since non-integral address spaces are not currently supported anyhow,
this does not introduce additional infidelity.

Summary:
Since Context treats only equality directly, formulas involving other
literals can normalize to false when the context is not unsat. This
diff changes Sh.star to check this case, and return the canonical
false symbolic heap.

Summary:
- Treat missing baseline files as if empty
- Only filter unchanged results if a baseline file is given
- Minor optimization
- Sort multiple statuses
- Fix total computation
- List tests with failing statues first
- Do not use `Format.formatter_of_out_channel` since it sometimes does
not work for some unknown reason, e.g. when the output should have
only one line, none are emitted.

Summary:
When exceptions are used due to the lack of goto, use `raise_notrace`
instead of `raise` to avoid the overhead of populating the backtrace.

Summary:
The implementation in Context, in terms of Fol.Term and Fol.Formula,
can now be used instead of Ses.Equality, implemented using
Ses.Term. The Ses modules can now be removed.

Apply normalization to conditional terms similar to conditional
formulas: evaluate terms with literal conditions, equal branches, and
ensure the condition is not negative.

fbshipit-source-id: f1eab822d
Summary:
The Fol.Term and Fol.Formula provide an interface which supports
if-then-else terms and formulas, while the underlying representation
in Trm does not and Fml only supports if-then-else over formulas, not
terms. The implementation of the rest of the first-order solver needs
to use the underlying, normalized, representation. This diff exports
Trm and Fml to separate modules for this purpose. Later, they will be
packed into a library for the first-order solver, and only used from
within.
