Summary: Have found this useful in Quandary for fbcode, where we want to do this for folly due to its use of assembly (details in comments).

Summary:
Now `infer analyze` really has the same behaviour as `infer -- analyze`.
Previously it wouldn't create report.json or report.

Summary:
This will be needed higher up in the stack because the new `ProcessPool` module
will need to call into `Logging` to refresh the logging formatters to get the
right PID when writing to the log file.

Summary:
For now, we just support clearing the taint on a return value.
Ideally, we would associate a kind with the sanitizer and only clear taint that matches that kind.
However, it's fairly complicated to make that work properly with footprint sources.
I have some ideas about how to do it with passthroughs instead, but let's just do the simple thing for now.

Summary:
1. `noexcept` was missing from `unique_ptr` constructors leading to compilation errors in some edge cases
2. In case `unique_ptr` specified custom deleter with custom `deleter::pointer`, there could be compilation errors due to invalid cast from `deleter::pointer` to `void*`. Add extra overload of `model_set` to prevent this issue

Summary:
This is a minimal change to (poorly) recognize and model std::mutex
lock and unlock methods, and to surface all thread safety issues for
C++ based on the computed summaries with no filtering.
This ignores much of the Java analysis, including everything about the
Threads domain. The S/N is comically low at this point.

This diff fixes unintentional bottoms in pointer arithmetic of inferbo.
The pointer arithmetic on addresses of variables (not array) just returns

Summary:
A recent diff tried to replace `L.out "error message"; assert false` with
`failwith "error message"` but infer relies on the type of raised exceptions to
sometimes keep going. A more careful change will be needed but in the meantime
restore the old behaviour.

Summary:
Recently we changed the binaries we build and use but it wasn't obvious that
some of the old binaries disappeared. For instance, nothing short of `git clean
-xfd` would get rid of "infer/bin/InferPrint", which can lead to frustrating
attempts to make InferPrint not segfault.
Mitigate this in two ways:
- be more strict in the binaries we ignore in .gitignore, so InferPrint would should up in "git status"
- be less strict in the binaries we clean out with `make clean` so that
InferPrint et al. gets deleted by `make clean`
