Sami Tolvanen 6b5dd716da objtool: optimize add_dead_ends for split sections 
Instead of iterating through all instructions to find the last
instruction each time .rela.discard.(un)reachable points beyond the
section, use find_insn to locate the last instruction by looking at
the last bytes of the section instead.
