1. Add support for temporary C++ objects.
2. Make constructor calls return constructed objects - it allows us pass them as parameters to another constructs (such as parameters, member expressions etc.)
3. Translate FunctionalCastExpr which sometimes is used instead of CXXTemporaryObjectExpr

Support MaterializeTemporaryExpr which happens often in real life C++.
For example, it will happen in this code:
std::vector<int> v;
v.push_back(1);
// it's because std::vector<int>::push_back(const int &)
Strategy is to create variable that will store value of init expression (to provide storage)
and then return variable as a result of an expression

Translate C++ overloaded operator calls. AST of their children looks slightly differently
which means that we have to be more permissive in params_trans.exps.
Difference:

MemberExpr:
'ThisExpr' (it's part of method decl ref evaluation)
MethodDeclRef
Param1
Param2

CXXOperatorCallExpr

Summary: public
C++ assignment operation result is lvalue, while in C it was rvalue.
This leads to different AST produced by clang for then same code!
Use language information from clang (`-x` flag) to distinguish these cases.
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
Reference:
http://en.cppreference.com/w/c/language/value_category (search for 'assignment and compound assignment operators')
NOTE: AST output doesn't change when something is hidden behind `extern "C"`, so we should use global language information

Summary: @public
This diff changes following things:
1. expression_info.type_ptr has type than decl_ref_info.type_ptr for reference types. Use type from decl_ref_info as a source of truth
2. reference types need to have one extra dereference that is not in AST. Add handling for this.
3. [small refactor] create function that creates temporary variable from res_trans expression and returns new res_trans.
Some caveats:
1. types are not quite right yet (see .dot files).
2. decl_ref_info might not be set for DeclRefExpr, make frontend crash in that case to catch when this happens
This is high risk change since it changes behavior of every translation on very widely used expr.
