Update documents for fcf-protection=
After r14-2692-g1c6231c05bdcca, the option is defined as EnumSet and
-fcf-protection=branch won't unset any others bits since they're in
different groups. So to override -fcf-protection, an explicit
-fcf-protection=none needs to be added and then with
-fcf-protection=XXX
