[PATCH 17/46] s390: Add .insn pseudo-mnemonics ril_a/b/c

This patch introduces support for the RIL-a, RIL-b, and RIL-c instruction formats on the s390 architecture using the .insn pseudo-mnemonic. It requires specific minimum architecture levels for each variant and adds tests for the rilu pseudo-mnemonic. The changes update opcode definitions and gas test suites.
