  Log Message:
  -----------
  [SystemZ] Make I5 operand of R[INOX]SGB(Z)? optional (#129512)

The I5 operand of the instructions in RIE-f format is optional and
assumed 0 when not specified. This was not properly modeled thus far,
and is corrected with this PR. In addition, assembly and disassembly
tests are updated to reflect these changes
