It's not used anywhere outside `VoidContext.qll`, where it was defined.
The use in `VoidContext.qll` is 10 years old and was a workaround for an
extractor bug that no longer exists.

C++: Fix up after merge from master
...
The one interesting piece that needed to be fixed up was the type of an `Indirect[Read|Write]SideEffect` operand/result. If the parameter type is a pointer or reference to an incomplete type, we need to set the type of the side effect memory access to `Unknown`, because we don't model incomplete types in the IR type system.
I also added minimal support for `__assume` (generated as a `NoOp`), because lack of `__assume` support got in the way of debugging the other issue above.

C++: Implement Pos and Spec as int, not newtype
...
This change gives a slight performance improvement and makes the QL code
shorter. It introduces some magic numbers in the code, but those are
confined to the `Pos` and `Spec` classes.
We get a speed-up because the evaluator has built-in support for integer
literals in the `OUTPUT` of `JOIN` operations, whereas `newtype`s have
to be explicitly joined on. As a result, a predicate like
`CFG::straightLineSparse#ffff` drops from 262 pipeline nodes to 242.
I measured performance on https://github.com/jluttine/suitesparse , which
is one of the projects that had the biggest slowdown when enabling the
QL CFG on lgtm.com. I took two measurements before this change and two
after. The `CFG.qll` stage took 117s and 112s before, and it took 106s
and 107s after.
