This header file contained tests for a bunch of fancy array handles so that they could be compiled for each device. These tests were bunched together because they were replicated for each device implementation, which was a hassle. However, having a bunch of tests crammed together is problematic for a number of reasons. The new testing no longer has a need to make a separate test for each device. Thus, the tests for the individual devices are removed, and the tests are split up and added to the basic vtkm_cont tests. In some cases, individual tests already existed there as well (probably because the developer did not see the test).
