Summary:
It's not necessary if compiling tests in infer environemnt. It may be required if compiling some C++ tests
without infer. `infer/tests/codetoanalyze/cpp/shared/attributes/depracated_hack.cpp` is one of them

Summary:
This changes executions of the former InferClang into a function call. In
particular, it can be called several times per execution.
The new InferClang must be called as if it was clang, and knows how to run
clang with our plugin to get the AST of the source file.

This changes the algorithm for pure join to keep the constraints that,
after normalization, occur in both arguments. Previously pure join
would normalize, filter, and then union the constraints of the
arguments.

Let's start migrating some of our bash script to OCaml to make them easier to
maintain and extend.
For now replace just one script and put it in lib/clang_wrappers/ at compile
time, where the former script used to be. Further simplifications will come
later.

Summary:
We were previously leaking the passthroughs of the callee into the caller.
We definitely don't want to do this since it could make the summaries higher up in the call stack explode.
If we need to know the passthroughs of a callee, we can always read them from the callee's summary.

Summary:
This diff fixes two issues in the backend that were causing Bad_footprint
errors when abducing pointsto facts for expressions that start in an array
access and follow up with another structured access, eg `x[0].some_field`:
1. array accesses were assumed to come last in these expressions
2. the type of the root exp passed to the function that walks down the list of
offsets to apply to it was wrong in the case of arrays: it was always the
type of the whole expression instead of the root expr (eg the type of
`x[0].some_field` instead of the type of `x`).

Summary:
This diff converts the Eradicate and Checkers tests to the new direct test format, which does not rely on buck or junit.
A self-contained Makefile is used to compile and analyze the test files, including all the dependencies, and a special option in InferPrint is used to produce a file of expected results `issues.exp`, which is checked into the repository.
Having an explicit Makefile makes it easy to edit and compile one set of test files in isolation, to investigate test failures, do debugging, etc.
A bunch of boilerplate code is removed. For example, the single file of expected results `issues.exp` replaces the 1.5K LOC in `endtoend/java/eradicate`.

Adding a new mode linters. Now if the analyzer is linters, we do the linters and don't translate,
then, if the analyzer is Infer, we do the translation and the backend and not the linters checks, and the
default is that we do capture, backend and lint checks.
Made the tests separated, which saves time and also shows that the linters mode works.
