Last option moved to opts.c

[Neil Booth <neil at daikokuya dot co dot uk>]

With this patch all options are handled in opts.c.  It contains a
short-term kludge for -finline-limit-, which I'll address properly
when I get round to doing target options, because the same issue
occurs in a few places there.

There is still some stuff happening in toplev.c, albeit under the
direction of opts.c now, such as handling -g options.  I think I'll
break those up into common.opt switches eventually.

Bootstrapping x86 NetBSD.

Neil.

	* common.opt: Add -finline-limit.
	* opts.c (common_handle_options): Handle it.
	* opts.sh: Temporary kludge for -finline-limit.
	* toplev.c (decode_f_option, independent_decode_option): Die.
	(parse_options_and_default_flags): No independent_decode_option.
