* s390x: update some regalloc metadata to remove use of `reg_mod`. This is a step toward ultimately removing modify-operands, which along with removal of pinned vregs, lets us move to a completely constraint-based and fully-SSA regalloc input and get some nice advantages eventually. There are still a few uses of `mod` operands and pinned vregs remaining, especially around the "regpair" abstraction. Those proved to be a bit trickier to update though, so will have to be done separately. * Review feedback: restore two-arg pretty-print form. * Review feedback.
