* avr-dis.c (comment_start): New variable, contains the prefix to use when
    printing addresses in comments.
  (print_insn_avr): Set comment_start to an empty space if there is no symbol
     table available as the generic address printing code will prefix the
     numeric value of the address with 0x.

	* avr-dis.c (avr_operand): Correct PR number in comment.

* avr-dis.c (avr_operand): Arrange for a comment to appear before the symolic
form of an address, so that the output of objdump -d can be reassembled.

	* avr-dis.c: Include libiberty.h (for xmalloc).
	(struct avr_opcodes_s): Remove 'bin_mask' field (it's
	automatically computed in the init routine).
	(AVR_INSN): No longer provide bin_mask field in initializer.
	(avr_opcodes_s): Declare as const.
	(print_insn_avr): Store the bin_mask field in a separate table
	(allocated with xmalloc); iterate through it at the same time as
	we iterate through the opcodes.

	Change return type from void to int.  Check the combination
	of operands, return 1 if valid.  Fix to avoid BUF overflow.
	Report undefined combinations of operands in COMMENT.
	Report internal errors to stderr.  Output the adiw/sbiw
	constant operand in both decimal and hex.
	(print_insn_avr): Disassemble ldd/std with displacement of 0
	as ld/st.  Check avr_operand () return value, handle invalid
	combinations of operands like unknown opcodes.

Add  -mall-opcodes, -mno-skip-bug, -mno-wrap.

	FMUL instruction.
	(reg_fmul_r): New. Extract source register from FMUL instruction.
	(reg_muls_d): New. Extract destination register from MULS instruction.
	(reg_muls_r): New. Extract source register from MULS instruction.
	(reg_movw_d): New. Extract destination register from MOVW instruction.
	(reg_movw_r): New. Extract source register from MOVW instruction.
	(print_insn_avr): Handle MOVW, MULS, MULSU, FMUL, FMULS, FMULSU,
	EICALL, EIJMP, LPM r,Z, ELPM r,Z, SPM, ESPM instructions.
