s390: Reduce the size of an s390_insn from 48 bytes to 32 bytes by
- adding one level of indirection for CDAS and DFP binops
- rearranging and tweaking the variant for helper calls
- using seperate insns kinds for signed and unsigned multiplication
  and division.
Add an assert to make sure the size stays at 32 bytes.
