* common.opt: Add driver options.

	(auxbase, auxbase-strip, quiet, version): Mark RejectDriver.
	* doc/options.texi (Driver, RejectDriver): Document.
	* gcc.c (pass_exit_codes, print_search_dirs, print_file_name,
	print_prog_name, print_multi_directory, print_sysroot,
	print_multi_os_directory, print_multi_lib,
	print_sysroot_headers_suffix, report_times, combine_flag,
	use_pipes, wrapper_string): Remove.
	(save_switch, driver_unknown_option_callback,
	driver_wrong_lang_callback, driver_post_handling_callback,
	driver_handle_option): New.
	(spec_lang, last_language_n_infiles): Make file-scope static
	instead of local to process_command.
	(process_command): Use decode_cmdline_options_to_array and
	read_cmdline_option for option processing.  Compute have_c in
	prescan of decoded options.
	* opt-functions.awk (switch_flags): Handle Driver and
	RejectDriver.
	(var_type, var_type_struct): Handle Separate options as generating
	const char * variables.
	* opts-common.c (decode_cmdline_option): Expect CL_COMMON and
	CL_TARGET to be passed by caller if required.
	(decode_cmdline_options_to_array): Update comment.
	* opts.c (complain_wrong_lang): Handle options only valid for the
	driver.
	(decode_options): Update call to decode_cmdline_options_to_array.
	(print_filtered_help): Ignore driver-only options.
	(print_specific_help): Ignore CL_DRIVER.
	(common_handle_option): Don't call print_specific_help for
	CL_DRIVER.
	* opts.h (CL_DRIVER, CL_REJECT_DRIVER): Define.
	(CL_PARAMS, CL_WARNING, CL_OPTIMIZATION, CL_TARGET, CL_COMMON):
	Update values.

c-family:
	* c.opt (MDX, MMDX, lang-asm): Mark RejectDriver.

fortran:
	* lang.opt (MDX, MMDX): Mark RejectDriver.

java:
	* lang.opt (MD_, MMD_, version): Mark RejectDriver.
