  -----------
  [SystemZ] Use getSignedConstant() where necessary (#117181)

This will avoid assertion failures once we disable implicit truncation
in getConstant().

Inside adjustSubwordCmp() I ended up suppressing the issue with an
explicit cast, because this code deals with a mix of unsigned and signed
immediates.
