cuda.sparse_gauss_seidel_asymmetric_rank1_kokkos_complex_double_int_int_TestExecSpace fails on kokkos-dev2 on clang/8.0/Cuda_OpenMP-release.

I think 16-byte alignment for complex<double> was disabled for clang previously, so maybe a Kokkos change caused this. The other possibility is that the version of MT GS that uses shared memory is misaligning scalar arrays, although it should have been seen before.

BTW, #645 is still happening (cuda.team_dot_complex_double fails in the same build).
