s390: Rename insn format VRR_0VVU to VRI_0VVU
Renames S/390 instruction format VRR_0VVU to VRI_0VVU to correct an earlier misclassification.
This patch corrects the naming of an S/390 instruction format, renaming VRR_0VVU to VRI_0VVU. The change aligns the format name with the official specification, as it was previously misclassified as VRR instead of VRI in an earlier commit. The opcode definitions and text files are updated accordingly for the vtz instruction.
In Details
This patch rectifies a misnaming of an instruction format for the S/390 architecture. The macro INSTR_VRR_0VVU (and its corresponding mask) is renamed to INSTR_VRI_0VVU. This correction aligns the format with the VRI-l specification, as it was erroneously tagged as VRR in a previous commit related to arch15 instructions. The change impacts the s390-opc.c and s390-opc.txt files, specifically for the vtz instruction.
