  [SystemZ] Change operand type for CKSM intrstruction. (#129572)

The current definition of the CKSM instruction uses GR64 for the first
operand. However, according to the Principles Of Operation the bits 0-31
of the first operand always remain unchanged. This PR changes the first
operand to GR32 to model this.
This has no further implication as this instruction is not used during
code generation.
