[PATCH 15/46] s390: Add .insn pseudo-mnemonics ri_a/b/c
This patch adds support for the RI-a, RI-b, and RI-c instruction formats on the s390 architecture using the .insn pseudo-mnemonic. These formats predate the IBM z900, so they share the same minimum architecture/CPU level as the base RI format. The changes include updating opcode definitions, adding comments to ESA/390 tests, and new test cases for z/Architecture.
