Summary:
If an aggregate `a` has a field `f` whose type has a constructor (e.g., `std::string`), we translate creating a local aggregate `A { "hi" }` as `string(&(a.f), "hi")`.
This diff makes sure that we recognize this as initializing `a`.

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:
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:
:
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.
