Hi,

    value class MyValue {
        MyValue other;
    }

A cyclic field is not aggressively scalarized, so when we obtain an object of 
`MyValue`, the field `other` stays as a `LoadP`. When we go `getfield` from a 
`MyValue`, we obtain the `LoadP` into the state map. We have 
`InlineTypeNode::adjust_scalarization_depth` but it only has its effect if the 
field is already an `InlineTypeNode`. We need to add a case to scalarize if the 
obtained field is an oop.

Many thanks to @TobiHartmann for the test case.

Please kindly review, thanks a lot.
