Summary:
Instrument SIL according to TOPL properties. Roughly, the
instrumentation is a set of calls into procedures that simulate a
nondeterministic automaton. For now, those procedures are NOP dummies.

Summary:
API and stub implementation for real-time logging capabilities.
Low-level implementation requires interaction with FB-specific deployment of Scribe, hence it is stubbed out.

Summary:
This ensures that each attribute type can only be present once per
address. Makes ~80x time improvement on pathological cases such as
Duff's device.
This introduces a new kind of Set in `PrettyPrintable`.

TOPL properties are essentially automata, which specify a bad pattern.

Summary:
It adds relational domains to Inferbo: octagon of Apron and polyhedra of Elina.
- Each `Mem` domain value includes one relational value containing relations among *symbols*. The relational values are modified by the `Prune` and `Store` commands.
- Each abstract value includes three *symbols*, which represent integer value, array offset, and array size of an abstract value.
The relational domain is deactivated by default, so this diff should not make any differences in CI.
Use `--bo-relational-domain {oct, poly}` for the activation, though Inferbo with the relational domains does not work at this point because some modifications of Apron and Elina we made has not been applied to their opam repositories yet.

Summary:
We inline the .ml and the .mli together using the .cmi rule (for reasons
explained in the Makefile of deadcode). This relies on the fact that rules will
start from the .cmx, which in turns depends on the .cmi as the last dependency
and so all the dependencies of the .cmx are satisfied by the time we hit the
.cmi. But that doesn't always work.
For some reason, making the .cmi depend on its .cmx works, even though it's
supposed to include a circular dependency (`make` should complain but doesn't).
Oh, well...

Summary:
There's actually a nice separation between IR/, base/, istd/, and the rest of
infer, so they can be made into separate jbuilder libraries so that the
separation remains. This helps make sense of the infer codebase.
Also:
- move everything biabduction-related out of backend/ and into a new
biabduction/ directory. This clarifies the current situation where backend/
contains a mix of analysis-independent code (still there now), and
biabduction-specific code (moved to biabduction/).
- move everything from base/ that is not infer-specific into istd/, e.g. IList.ml
- kill unused `FbTraceCalls`
- A couple of files needed to move around to complete the separation of base/ and IR/
