	PR target/61578
	* ira-color.c (update_allocno_cost): Add parameter.

	parameter.

From-SVN: r228097

Actually, I was trying to reject non-warning options as argument to
-Werror=. However, the new test fails because -fdiagnostics-color=never is
always placed by the driver after the warning options when calling the compiler
proper. This patch prunes all -fdiagnostics-color from the command-line but the
last one, which is moved to the first position.
