C++ assignment operation result is lvalue, while in C it was rvalue.

More specifically, let's look at following code:
int r;
int f = (r = 3);
// type of (r = 3) expression:
// C/objC -> int rvalue
// C++/objC++ -> int lvalue
Existing code did extra dereference because it was rvalue in C and there was no cast afterwards
in C++ there will be extra LValueToRvalue cast when neccesary so we don't have to do extra dereference manually

Summary: public Two cases were not handled properly so far:
1. Declaration of a reference variable missed reference bit in type
2. Parameters to a function expecting T& had type T.
The way to distinguish reference types from value types is to look
whether parameter is type 'T rvalue' or type 'T lvalue' (xvalue probably as well)
Unfortunately, we can't just say 'T lvalue' = 'T&' because it would break
a lot of things in our frontend.
However, we know that when parameter to a function call has type 'T lvalue', it has to be 'T&' type.
Same applies when init_expression type is lvalue.
So, the solution is to add wrapper function that looks at results of `instruction` function and
expected expression type. Then if it's lvalue, wrap the type in reference.
Do this wrapping magic only when we know that lvalue mean reference type.
The rest of the changes is to make frontend tests pass - since we use different fields
in the AST, some of them were incorrectly set before and no one noticed.

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:
frontend and backend assume that Sil.Struct
doesn't have methods nor inheritance. In order to plug C++
classes we probably need them to be Sil.Class
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:
This is the second of 3 stack diffs to deal with replacing the parser of types.
This diff is about changes to translate record types, as well as class types and enum
types. For class types and enum types we store the declaration pointer in the map of
types to find the type easier later.
For record declarations, we change the way we build record names.
Moreover, we don't translate typedefs anymore, because when we have a pointer to a typedef,
we can find the actual type it points to.
Summary:
each procedure has a different scope, so we can restart the fresh name generator and have more stable instructions in the cfg, that don't change when other procedures are changed
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
