This patch simplifies process_command a bit by using save_switch and
sets the "known" switch field to "true".


gcc/ChangeLog:

2012-10-05  Dmitry Gorbachev  <d.g.gorbachev@gmail.com>

	PR driver/54789
	* gcc.c (process_command): Use save_switch for synthesized
	-fcompare-debug=* option; mark the switch as known.

Applied after bootstrap/regtested on x86_64-linux and i686-linux and
