This activates the linear-work suffix sorting from PR #32 along with some minor changes to get testing to pass.

I observed this to significantly improve suffix array constructions for large problem sizes. E.g. previously a 4GB test went at 16 MB/s but after this change it goes at 25 MB/s.

Future Work: use the old implementation for small enough problems.
