[ELF] - Do not change binding of symbols when creating relocatable output. Spec says "A hidden symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object". But we previously converted symbols to STB_LOCAL even when -r was specified. Broken binary was produced, this is PR28967, patch fixes the issue. Differential revision: https://reviews.llvm.org/D23514 llvm-svn: 279220

[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
