Summary:
In ObjC there are no access modifiers. The strongest alternative is to put methods in the implementation but omit them from the interface declaration.
Put exported ObjC methods in their own field in the class structure and use that in RacerD to decide whether to report on the method.

Summary:
It suppresses intended integer overflows that generate hash values or random numbers. For judging that the intention of integer overflow, it applies a heuristics: checking if traces of issues include a whitelisted words, e.g., "rand" or "seed".
While we would be able to suppress all integer overflows of unsigned integers since they have defined behaviors, we don't want to miss unintended integer overflows, e.g., that on unsigned index value.

- `Printer.NodesHtml.start_node` prints the instructions rather than doing it in the callee
- use color class for `<LISTING>` rather than wrapping them in `<span>` (also fixes a wrong nesting between `<LISTING>` and `<span>`)
- `Summary.pp_html` is always `Black`
- New line before `<hr>` and `<LISTING>`

Summary:
Split into:
- `PulseDiagnostic`, formerly `PulseDomain.Diagnostic`
- `PulseOperations`, formerly `PulseDomain.Operations`
This breaks down the now quite large and complex PulseDomain.ml into
more manageable pieces. More importantly, it will allow us to build a
bigger pulse domain later, where elements of the domain are pairs of the
base domain that include a biabductive "footprint".
What's not as nice is that more of the interface of `PulseDomain` is
exposed, in particular `PulseDomain.Memory` and `PulseDomain.Stack`.
We'll have to be careful not to break abstraction barriers and prefer
`PulseOperations` to `PulseDomain` outside of the domain implementation.
OCaml forces us to do that because of the multi-file approach. It could
be solved by introducing pulse domains as a library but who has time for
that...
Sending early because rebasing that diff is painful.

Summary:
Record per-location traces. Actually, that doesn't quite make sense as a
location can be accessed in many ways, so associate a trace to each
*edge* in the memory graph. For instance, when doing `x->f = *y`, we
want to take the history of the `<val of y> --*--> ..` edge, add "assigned
at location blah" to it and store this extended history to the edge
`<val of x> --f--> ..`.
Use this machinery to print nicer traces in `infer explore` and better
error messages too (include the last assignment, like biabduction
messages).
