[PATCH 43/46] s390: Add .insn pseudo-mnemonics vrs_a/b/c/d

This patch adds support for four variants of the VRS instruction format (vrs_a, vrs_b, vrs_c, and vrs_d) to the s390 gas assembler using the ‘.insn’ pseudo-mnemonic. These variants were introduced in IBM processor generations z13 and z14. The changes include updates to opcode definitions, documentation, and test suites.
