* sparc-dis.c (print_insn_sparc): NUMOPCODES replaced with
sparc_num_opcodes. Update architecture enum values.
* sparc-opc.c (sparc_opcode_archs): Replaces architecture_pname.
(sparc_opcode_lookup_arch): New function.
(sparc_num_opcodes): Renamed from bfd_sparc_num_opcodes.
(sparc_opcodes): Add v9a shutdown insn.
