Handle copy relocations in symbol assignments. When a linker script has "foo = bar" and bar is the result of a copy relocation foo should point to the same location in .bss. This is part of a growing evidence that copy relocations should be implemented by using replaceSymbol to replace the SharedSymbol with a Defined. llvm-svn: 319449

[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651
