[PATCH 42/46] s390: Add .insn pseudo-mnemonics vrr_a/b/c/d/e/f/g/h/i/j/k
This patch adds support for eleven variants of the VRR instruction format (vrr_a through vrr_k) to the s390 gas assembler using the ‘.insn’ directive. These variants were introduced across different IBM processor generations (z13, z14, z15, z16, z17). The changes include updates to opcode definitions, documentation, and test suites.
