Make psh/pul error out if no registers given While the generated object code was technically correct for bare pshs, puls, pshu, and pulu, it was not helpful. Throw a bad operand error if no registers are given as an operand to such instructions. Thanks to Erik G <erik@6809.org> for reporting the problem.
