Disable No-Arg Constructors in Classes

Code sample:
```
struct SomeStruct {
@disable this();
this(int arg) {
}
}
class SomeClass {
private:
SomeStruct _stuff;
public:
this() {
_stuff = SomeStruct(10);
}
}
void someFunc() {
SomeClass obj = new SomeClass(); // Error: default construction is
disabled for type SomeClass
}
```
As you can see, the @disabled constructor in SomeStruct breaks the no-arg
constructor in SomeClass.
Disabling the *default* constructor in SomeClass is correct, but if a no-arg
constructor is implemented, it should be checked against the same rules as
other constructors (and an error should occur if it doesn't initialize the
@disabled struct).
