Looks okay in general.   For the new methods like `isValue`, `valueType` and `putValueClass` etc, they should be renamed to reflect the new terminology (inline class).

I think we should rename `isValue` to `isInlineClass` and also other new `xxxValue` methods

Are these two `loadCode` methods taking a builder `Consumer` used by the tests?

If so, the following classes and methods can be made private to hide them as internals.
