> We are currently not handling inline types in the `clone()` instrinsic because it was not possible for a value class to implement `Cloneable`. This changed with [JDK-8332243](https://bugs.openjdk.org/browse/JDK-8332243). A value class now trivially returns the inline type because it has no identity. We need to do the same in the C2 intrinsic for `clone()` when we have an inline type (currently, we are hitting an assert later).
