  [SystemZ] Require D12 for i128 accesses in isLegalAddressingMode() (#79221)

Machines with vector support handle i128 in vector registers and
therefore only have the small displacement available for memory
accesses. Update isLegalAddressingMode() to reflect this.

(cherry picked from commit 84dcf3d35b6ea8d8b6c34bc9cf21135863c47b8c)
