Bug fixes:
*) method reference bridge generation in the inner class translation doesn't handle varargs correctly
*) enclosing instance check on explicit inner constructor reference is bogus
Enhancements
*) 'raw' constructor reference will cause diamond inference to kick in
//example 1 - inference from arguments
interface SAM1 {
    void m(Integer s);
}

class Foo<X> {
   Foo(X x) { }
}

Foo<?> f = Foo::new; //Foo<Integer>::new inferred

//example 2 - inference from return type
interface SAM2 {
    Integer m();
}

class Bar<X> { }

Bar<String> f = Bar::new; //Bar<String>::new inferred
