Fix #1048: handle mode C spmv correctly in serial/openmp #1084
Conversation
- Testing: have IOUtils sparse matrix generator use getRandomBounds() and the Kokkos PRNG, so that complex values actually have nonzero imaginary component. Before, it was always 0, so mode N and C spmvs were equivalent and this was never caught by testing. - Serial: in unrolled impl, conjugate A's values in mode C - OpenMP: just don't use the special omp impl in mode C (this kernel is pretty much never called in practice anyway, see comment in code)
