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.
