Thanks for your contribution @sbcd90. I think the PR needs still a bit of
work before it can be merged. The implementation of `GenericArrayComparator`
only works for primitive types. Furthermore, I think that it is easier to
construct the comparator out of the component type information of the
`ObjectArrayTypeInfo` instead of doing the type analysis again every time you
call `compare`.
