Summary:
Instrument SIL according to TOPL properties. Roughly, the
instrumentation is a set of calls into procedures that simulate a
nondeterministic automaton. For now, those procedures are NOP dummies.

Summary:
When multiple buck java tests use the same `buck-out` they sometimes fail. This isn't surprising, as they presumably clobber each other's output when running on the same files.
Since there is no reason to have this global, shared buck repo, create one for each test, inside the test directory. Also, clean up the Makefiles a bit -- they provide bogus compile targets, for example, and have mostly wrong source dependencies.
That done, remove the `testlock` crutch which enforces mutual exclusion between tests, from the buck/java tests.
I do not understand why the buck clang tests can share the global repo without failure, but there you go.

Summary:
It is unsafe to call protocol methods defined optional. Before calling them we should check it
the implementation exists by calling
`if ([object respondsToSelector:selector(...)]) ...`
Without the above check we get run time crashes.

Somehow clang now chooses slightly different arguments to pass to `ld`

In particular:
- `lc++` results in `libc++.so` not found from the toolchain
- the forced relocation `-z relro` fails with "/..//bin/ld: ./obj/local/arm64-v8a/objs/hello/__/hello.o: Relocations in generic ELF (EM: 183)" and other weirder errors
Somehow pretending the C++ compiler is `clang` instead of `clang++` stops the insanity.
Also add an Application.mk file to specify some sane defaults.
Also add `V=1` to the `ndk-build` invocation in our tests so that when it fails we have a bit more to work with.

Summary:
- Rename `invariantModels` to `purityModels`
- Track which arguments are modified in purity models. Before we were invalidating all arguments of impure modeled functions. Instead, now we only invalidate modified args given in the model. This should ideally result in more precision in the analysis.
- Add some more purity models for :`cast`, `new`, `new_array` and `Math.random`

Summary:
`infer_events` table is a key-value storage that also have list of fields common for entire infer run.
Infer should be agnostic of many of such fields (e.g. diff number).
Hence we will pass such extra fields through CI.
Note that only "normals" (strings in scuba terminology) are currently supported.
Reason being: most of things that are technically ints (like IDs) should actually be normals (because average etc does not make sense for them; and group by, in contrast, does).
