gdb/
        * disasm.c (dump_insns): Support dumping opcodes for MI.
        * mi/mi-cmd-disas.c (mi_cmd_disassemble): Allow mode to control
        dumping of instruction opcodes.

gdb/doc/
        * gdb.texinfo (GDB/MI Data Manipulation): Update to reflect
        changes in mi/mi-cmd-disas.c

gdb/testsuite/
        * gdb.mi/mi-disassemble.exp, gdb.mi/mi2-disassemble.exp: Update
        expected output to reflect changes in gdb/mi/mi-cmd-disas.c and
        add new tests for opcode dumping.
