struct Foo
{
    int x;

    ref noReturnType()
    {
        return x;
    }
}

void main()
{
    auto foo = Foo();
    foo.noReturnType = 5;
    assert(foo.x == 5);
}

Should this be allowed? It doesn't make much sense, especially when you can
write code like this:

struct Foo
{
    ref noReturnType()
    {
        return 1;  // does an rvalue return
    }
}

void main()
{
    auto foo = Foo();
    auto x = foo.noReturnType();
}

This compiles and only confuses the reader.

This happens because there is no actual storage class for auto ref, it just
becomes auto ref when it is both auto and ref.

Additional fix for issue 6905

For the inference of return value ref-ness, we should use 'auto ref' instead of
'ref' or 'const ref'
