Do not print out removed ICF sections for -verbose. GNU gold doesn't print out ICF sections for -verbose. It only shows them for -print-icf-sections. We printed out them for -verbose because we didn't have -print-icf-sections. Now that we have the option, there's no reason to print out for -verbose.
