Add support for explicit constructor calls in Microsoft mode.
For example:
class A{
public:
A& operator=(const A& that) {
if (this != &that) {
this->A::~A();
this->A::A(that); // <=== explicit constructor call.
}
return *this;
}
};
More work will be needed to support an explicit call to a template constructor.
