This is an initial version of the Expensive checker which only report violations on direct calls. The main objective is to setup all the files for this new checker.
The next steps are:
1) run the checker in interprocedural mode
2) Save in the summary of a method foo() the annotation attribute Expensive if a direct callee of foo is annotated with Expensive
3) Check that Expensive is enforced by subtyping, i.e. check that non-expensive method cannot be overwritten by a method annotated with Expensive

paths look a bit silly prior to this diff, as they go up from infer/ to go back

This changes this path to the less silly:

The progress bar for the analysing procedures part is just printing dots at the moment and will be
improved soon when we do all the multithreading inside Ocaml.
There is also a no_progress_bar option in the scripts to hide it, for instance in CI.

Summary: public
Type of `this` argument to c++ method call has pointer type.
It's either raw pointer (for `->`) or reference (for `.`).
It was already correct in method declaration and method parameters, but it wasn't correct in method calls. Same thing will apply to constructor expressions.
As a result of this change, we won't expand type when calling methods.
Change to ast_expressions.ml fixes problem with autogenerating getters/setters that produced lvalue types after LValueToRValue cast.

Summary: public
Adding initial support for Buck for Cxx on the toplevel infer command.
If a `cxx_binary`/`cxx_library` builds with the command `buck build //targetName:target` then the analysis of Infer can be triggered through the `#infer` flavor.
This change configures buck to run Infer, whenever the `#infer` flavor gets passed: just run
`infer --use-flavors -- buck build //targetName:target#infer`
Please note that when using this feature (`--use-flavors`), the toplevel `infer` command has to be launched from the root of the buck project (which is where the `.buckconfig` file is located) and the `#infer` flavor must be passed on the target.

Summary: public Translate classes and protocols on demand only.
This saves space in the tenv and time. The categories still cannot be translated on demand
because there is no pointer to them from the classes. Andrzej is fixing that.
We had to make cTypes_Decl and the modules for translating classes, protocols and categories mutually
recursive. Moreover, we had to reorder the method for adding classes to the tenv to receive a decl and
return a type.
