Summary: @public
1. Add support for `this` keyword. It will allow to access fields/methods of the object from the method body.
2. Fix problem with method formals to add pointer to type of first parameter (which corresponds to `this`)

2. Create new directory with smaller .cpp files to translate

Summary: @public
First diff to give better language information in the frontend.
This information is necessary to understand when 'self' is objc keyword,
when 'this' is C++ keyword and when they are not.

Summary:
In the new clang the parameters to these functions have notnull annotations, because of that infer tests fail. More concretely, the tests say there would be a memory leak. In the symbolic execution of those functions though, an inconsistency is created, because the parameter was nil, and the constraint argument should not be nil was also there, which leads to an error in the execution and no object is created, hence, no memory leak.
Summary:
Pass inheritance information to the backend
It also changes some functions in cTypes_decl and we are using type and decl maps to resolve these types
Summary:
Handle C++ method declarations and create cfgs for them.
Doesn't do:
Method calls (CXXMethodCall)
Using `this` expression in methods (including implicit ones)
Summary:
Add basic translation for C++ `new` keyword.
Currently, it's modeled as simple `malloc` call.
Following constructs are still not working properly:
- array new `new [size_expr]`
- run initializer attached to `new` (such as `new int(5)`)
- `delete[]`
Summary:
In objC we already prefix field names with classes.
It's better to make it consistent since it'll allow
us to share more code between C++ and objC
Summary:
@public
Add support for default function arguments.
As a side change - always create cmethod_signature for a function
Test Plan:
1. Call function with default parameter and confirm that it gets parsed and reports null dereference (B5 but still). It didn't before.
2. Created a test case
Summary:

Translate CXXStaticCastExpr
Test Plan:
Add test, confirm that it gets translated.
Also create example to see that infer reports null dereference with this change:
struct X { int a; };
int main() {
X *x = static_cast<X*>(nullptr); // <- reports now
//X *x = (X*)nullptr; // <- reported before
return x->a;
}
Summary:
@public
Make c frontend understand CXXNullPtrLiteralExpr.
Note that the implementation differs from GNUNullExpr
Test Plan:
Create function that returns nullptr:
int* getPtr() {return nullptr;}
look at specs:
