Data.Array.Parallel.Unlifted.ArrayArray

Irregular 2D unboxed arrays.

The difference between this type and something like Data.Vector (Data.Vector.Unboxed a) is that the inner arrays have kind # and cannot be bottom. This ensures that we can always lookup an element from an ArrayArray# without performing unboxings or checking for thunks.
