i386: add 'final' and 'override' to scalar_chain

In c3ed9e0d6e96d8697e4bab994f8acbc5506240ee, David added some
"final override" and since that there are 2 new warnings that
need the same treatment:

gcc/config/i386/i386-features.h:186:8: warning: 'convert_op' overrides a member function but is not marked 'override' [-Winconsistent-missing-override]
gcc/config/i386/i386-features.h:186:8: warning: 'convert_op' overrides a member function but is not marked 'override' [-Winconsistent-missing-override]
gcc/config/i386/i386-features.h:199:8: warning: 'convert_op' overrides a member function but is not marked 'override' [-Winconsistent-missing-override]
gcc/config/i386/i386-features.h:199:8: warning: 'convert_op' overrides a member function but is not marked 'override' [-Winconsistent-missing-override]

gcc/ChangeLog:

	* config/i386/i386-features.h (class general_scalar_chain): Add
	  final override for a method.
	(class timode_scalar_chain): Likewise.
