Port D69671 (llvm-readobj) to llvm-objdump. Add a class llvm::objdump::Dumper and move some free functions into Dumper so that they can call reportUniqueWarning. Warnings seems preferable in these cases as the issue is localized and we can continue dumping other information. Differential Revision: https://reviews.llvm.org/D154754
