Summary:
Make std::shared_ptr<T> translated as T* inside infer. This will make reporting better
since smart pointers are really pointers not structs - this form is much easier for the analyzer to understand.
This requires changes to the model of shared_ptr as well.

Summary:
Infer doesn't go looking into field values when looking for unsigned
expressions, which could cause some unintended reports.

Summary:
This helps avoid some unintended reports where the actual is known to point to
a specific object before a call to a skipped function. This requires a change
in the plugin to export more info about const types.

Summary:
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.

Summary:
Make checks context-aware, to increase flexibility.
As an example application of this change, whenever an atomic property is accessed from within a synchronized block, skip reporting a `DIRECT_ATOMIC_PROPERTY_ACCESS` warning.

Summary:
Previously, we would translate `throw` with `return`. However, `throw` in
ObjC/C++ is often used to mean "abort". We now translate `throw` the same as
`exit` to prune these paths.

No longer allow pointer types to be passed inside var_exp_typ. We used to accept both forms,

Summary:
When analyzing C model in C++, we were seeing some SKIP function triggered by generated constructors/operators= for C structs.
In C they weren't present, but in C++ compiler generates them for us. To avoid this (and future) problems
with models, translate all functions that are needed when computing the model

This call was producing confusing false positives when deleted object was possible to be null.
Changing frontend to add that check is not trivial so I turned it off for now (we don't handle
destructors in other cases anyway)

Summary:
When clang instantiates template function with argument pack, it will
give the same name to all parameters coming from the pack. To avoid
name collisions, always add index of argument's position to mangled part
of the variable.
Seemingly unrelated changes are to make existing tests pass (don't use
simple variable name where it matters)
