[Issue 23947] If a class overloads a method mixing private and public and the last overload is public, the method is always public.

Correction: more testing suggests that the accepts-invalid condition is "the
method is private, but a method defined after it in the overload set is
public". Doesn't have to be the last one.

Consider: this compiles.

struct X { }
struct Y { }
struct Z { }
class Class {
    private void handle(X x) { }
    public void handle(Y y) { }
    private void handle(Z z) { }
}
