The FFT_BC_* class of a poisson_bc_code case, or FFT_BC_UNSUPPORTED. The CUDA solver passes it to the helpers it shares with x3d2-memcheck, so it classifies through poisson_bc_code alone. x3d2-memcheck has no mesh and takes the class from m_mesh's classify_boundaries; test_poisson_bc_code checks that the two agree.
