Both of these require sm_30, so from that perspective we won't leave any architectures behind. OTOH, this may leave behind: - some older drivers - some older CUDAs (if ptxas is used for ptx verification in the nvptx-none-as). Rerunning the entire testsuite though shows that the non-32-vector-length test-cases are still failing.=
