common.opt (exit_after_options, [...]): New Variable entries. 

* common.opt (exit_after_options, write_symbols, debug_info_level,
	use_gnu_debug_info_extensions): New Variable entries.
	(fprofile-dir=): Use Var.
	* flag-types.h (enum debug_info_level): Rename to enum
	debug_info_levels.
	* flags.h (write_symbols, debug_info_level,
