Use disassemble_info.private_data in place of insn_sets

Use disassemble_info.private_data in place of insn_sets

No cgen target uses private_data.  This patch removes a
disassemble_info field that is only used by cgen, and instead uses
private_data.  It also removes a macro that is no longer used.
