This is an intermediate and fairly mechanical step towards unifying the benchmarks with the rest of the test suite. Moving this around requires a few changes, notably making sure we don't throw a wrench into the discovery process of the normal test suite. This won't be a problem anymore once benchmarks are taken into account by the test setup out of the box.
