Cary Coutant 651d162038 Fix bug with relocation addends and merge sections with --icf. 
During --icf processing, gold was incorrectly processing the relocation
addend for references to items in a merge section. PC-relative references
and other forms of reference with a biased base address require a
non-section local symbol, where the addend is purely the bias.
