Summary:
At the moment, Java and Clang sources/sinks live in the same inferconfig entry.
If we try to parse a Java procedure that happens to be an invalid Clang qualified name (e.g., `MyClass.<init>`),
parsing will crash.
As a temporary fix, throw an exception and catch it instead.
In the future, we can avoid this by requiring that JSON source/sink specifications to indicate the language.

Summary:
- Rather than passing a directory name to PerfStats reporting api to write the stats to, and then determining the EventLogger `stats_type` from that dirname, there is now a `stats_type` type in PerfStats, and the directory name and EventLogger tag is automatically determined from that type after it is passed to the API
- This allows us to determine whether we're in capture mode or linters mode dynamically from PerfStats itself, and use the appropriate tag when creating an event

Summary:
Aggregate initialization (e.g., `S s{1, 2}`) doesn't invoke a contructor.
Our frontend translates aggregation initialization as assigning to each field in the struct.
To avoid the appearance of the struct being uninitialized, count any assignment to a field of an aggregate struct as initializing the struct.

Summary: Backend perf stats were previously being logged as both `driver_stats` and `backend_stats`. Now they are correctly logged only as `backend_stats`, and a single `driver_stats` exists for the top-level driver process.

Summary:
Previously, `backend_stats` were getting logged correctly only when `infer analyze` was directly called, not `infer run`. Now, we report `backend_stats` directly, as part of the `iterate_callbacks` function in the task passed to the `ProcessPool`.
As a side benefit, `aggregated_stats` are also logged correctly now.

Summary:
:
Previously, we did not have information about type of `exp` in `sizeof exp` from clang plugin which led to `Bad_footprint` errors. Infer did not understand `sizeof *p` in `struct Person* p = malloc(sizeof *p);` and used some default type.
This resulted in `Bad_footprint` error when trying to assign to a field `age` in `p->age=42;`.
This diff uses the version of clang plugin which exports the appropriate type information.

- Contains some of the information logged to disk by PerfStats, as well as a `stats_type` tag to indicate which type of process the stats are from
