Summary:
The C++ tests were a bit of a mess. This diff tries to enforce the following principles:
- mark every function with `_ok` or `_bad` so that when a function appears in `issues.exp` it's easy to figure out the intention;
- mark every false negative and positive with `FP_` and `FN_` to document expectations;
- make every function access one field and participate in at most one issue report so that it's easier to assess changes.

Summary:
To emulate the `ThreadSafe` contract in C++/ObjC, reporting was gated behind a check that ensured a C++/ObjC class has a `std::mutex` member (plus other filters). This is reasonable, but it has some drawbacks
- other locks may be used, and therefore must be added to the member check;
- locking mechanisms that use the object itself as a monitor cannot be modelled (`synchronized` in ObjC)
RacerD already has `ThreadsDomain` which models our guess on whether a method is expected to run in a concurrent context, and which in C++/ObjC boils down to whether the method non-transitively acquires a lock. This should be a good enough indicator that the class should be checked regardless of whether the locks are member fields. This diff gates the C++/ObjC check on that abstract property.
