* 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.
