* cli/cli-cmds.c (disassemble_command): Add a new modifier /r
	to "disassemble" command to print the raw instructions in hex as
	well as in symbolic form.
	(init_cli_cmds): Ditto.
	(print_disassembly): Change "mixed" to "flags" to translate
	the behavior of disassemble.
	(disassemble_current_function): Ditto.
	* mi/mi-cmd-disas.c (mi_cmd_disassemble): Ditto.
	* stack.c (gdb_disassembly_stub): Ditto.
	* disasm.c (do_mixed_source_and_assembly): Ditto.
	(do_mixed_source_and_assembly): Ditto.
	(do_assembly_only): Ditto.
	(gdb_disassembly): Ditto.
	(dump_insns): print the raw instructions in hex as well as in
	symbolic form if DISASSEMBLY_RAW_INSN and flags is true.
	* disasm.h (DISASSEMBLY_SOURCE): Include source code with the
	assembly if it and flags is true.
	(DISASSEMBLY_RAW_INSN): Include the raw instructions in hex with
	the assembly if it and flags is true.
	(gdb_disassembly): Update extern.
	* NEWS: Document disassemble/r support.
