Fix problems when bfd_vma is wider than long.
	* i386-dis.c: Make op_address and start_pc unsigned.
	(set_op): Make parameter unsigned.
	(print_insn_x86): Cast to bfd_vma when passing a value to
	print_address_func.
	* ns32k-dis.c (CORE_ADDR): Don't define.
 	(print_insn_ns32k): Change type of addr to bfd_vma.  Use
	bfd_scan_vma to read back address.
	(print_insn_arg): Change type of addr to bfd_vma.  Use sprintf_vma
	to format it.
	* m68k-dis.c (COERCE32): Cast to bfd_signed_vma to avoid overflow.
	(NEXTULONG): New definition.
	(print_insn_m68k): Avoid overflow when computing third argument of
	print_insn_arg.
	(print_insn_arg): Use NEXTULONG to fetch 32 bit address values.
	Use disp instead of val to store offset values.
	(print_indexed): Use base_disp instead of word to store base
	displacement, to avoid overflow.
	* m10300-dis.c (disassemble): Cast value to long when computing
	pc-relative address, to get correct sign extension.
