[llvm-readelf] Make llvm-readelf more compatible with GNU readelf.
Summary: This change adds a bunch of options that GNU readelf supports. There is one breaking change when invoked as `llvm-readobj`, and three breaking changes when invoked as `llvm-readelf`: - Add --all (implies --file-header, --program-headers, etc.) - [Breaking] -a is --all instead of --arm-attributes - Add --file-header as an alias for --file-headers - Replace --sections with --sections-headers, keeping --sections as an alias for it - Add --relocs as an alias for --relocations - Add --dynamic as an alias for --dynamic-table - Add --segments as an alias for --program-headers - Add --section-groups as an alias for --elf-section-groups - Add --dyn-syms as an alias for --dyn-symbols - Add --syms as an alias for --symbols - Add --histogram as an alias for --elf-hash-histogram - [Breaking] When invoked as `llvm-readelf`, -s is --symbols instead of --sections - [Breaking] When invoked as `llvm-readelf`, -t is no longer an alias for --symbols Reviewers: MaskRay, phosek, mcgrathr, jhenderson Reviewed By: MaskRay, jhenderson Subscribers: sbc100, aheejin, edd, jhenderson, silvas, echristo, compnerd, kristina, javed.absar, kristof.beyls, llvm-commits, Bigcheese Differential Revision: https://reviews.llvm.org/D54124 llvm-svn: 346685
