ELF: Fix ICF crash on absolute symbol relocations. If two sections contained relocations to absolute symbols with the same value we would crash when trying to access their sections. Add a check that both symbols point to sections before accessing their sections, and treat absolute symbols as equal if their values are equal.

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.
