* opts.h (cl_option): Add comments to fields. Add bit-fields for

	various flags.
	(CL_SEPARATE_NARGS_SHIFT, CL_SEPARATE_NARGS_MASK,
	CL_SEPARATE_ALIAS, CL_NO_DRIVER_ARG, CL_REJECT_DRIVER, CL_SAVE,
	CL_DISABLED, CL_REPOR, CL_REJECT_NEGATIVE, CL_MISSING_OK,
	CL_UINTEGER, CL_NEGATIVE_ALIAS): Remove.
	(CL_JOINED, CL_SEPARATE, CL_UNDOCUMENTED): Update bit positions.
	* opt-functions.awk (flag_init, switch_bit_fields): New.
	(switch_flags): Don't handle flags moved to bit-fields.  Don't
	generate CL_MISSING_OK or CL_SAVE.
	* optc-gen.awk: Update to generate bit-field output as well as
	flags field.
	* gcc.c (driver_wrong_lang_callback): Use cl_reject_driver
	bit-field instead of CL_REJECT_DRIVER flag.
	* opts-common.c (generate_canonical_option,
	decode_cmdline_option): Use bit-fields instead of CL_* flags.
	* opts.c (maybe_default_option): Use cl_reject_negative bit-field
	instead of CL_REJECT_NEGATIVE flag.
	* toplev.c (print_switch_values): Use cl_report bit-field instead
	of CL_REPORT flag.
