Initial implementation of flat arrays in the lworld model was design with a single flat layout in mind. With the introduction of multiple flat layout (NON_ATOMIC_FLAT, ATOMIC_FLAT, NULLABLE_ATOMIC_FLAT), flat arrays have to be redesigned and all their access code updated.
The current design of flat arrays also have remains of the time where the VM was using Q-descriptors. This has to be removed.
