 	max to 64bits, expect trouble.  Make the default 32 bits.
	* gen-idecode.c (print_idecode_table): Change EXTRACTED*
 	et.al. macro's to use the insn_bit_size instead of assuming 32
 	bits.
	* gen-icache.c (print_icache_extraction): Ditto.
	* gen-idecode.c (idecode_switch_start): Ditto.
	* gen-idecode.c (gen_idecode_c): Ditto

	* igen.h (insn_specifying_widths), igen.c (main): New option -W.
  	Indicates that the instruction field of the table is specifying
 	bit widths instead of bit offsets.
	* ld-insn.c (parse_insn_format): Parse instruction fields
 	specifying widths.

	* misc.c (a2i): Allow binary numbers to be specified using the
 	syntax 0bNNNN.
	* ld-insn.c: Allow such numbers to appear in the instruction
 	format.

	* table.c (table_entry_read): Make // a valid comment character.
	(table_entry_read): Skip lines containing a leading " - these may
 	eventually be used in a disasembler.
