Rui Ueyama ed64342b67 Retry submitting r186623: COFFDumper: Dump data directory entries.
The original change was rolled back in r186627 because of test
failures on the big endian machine. I believe I fixed the issue
so re-submitting.

Rui Ueyama f388243037 Revert "COFFDumper: Dump data directory entries."
Because it broke s390x and ppc64-linux buildbots. This reverts commit r186623.

Rui Ueyama a20b9f52d4 COFFDumper: Dump data directory entries.
Summary:
Dump optional data directory entries in the PE/COFF header, so that
we can test the output of LLD linker. This patch updates the test binary
file, but the source of the binary is the same. I just re-linked the file.
I don't know how the previous file was linked, but the previous file did
not have any data directory entries for some reason.

Benjamin Kramer 48b6a881be COFFDumper: Print uint64_t with the right format string.
I wish we could typecheck llvm::format.

Rui Ueyama 82ebd8e36d readobj: Dump PE/COFF optional records.
These records are mandatory for executables and are used by the loader.

Rafael Espindola 806f006490 Handle relocations that don't point to symbols.
In ELF (as in MachO), not all relocations point to symbols. Represent this
properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj
ELF's dumper to handle relocatios without symbols.

Nico Rieck f3f0b79704 Add -expand-relocs to llvm-readobj
This option expands shown relocations from single line to a dictionary
format:

  Relocation {
    Offset: 0x4
    Type: R_386_32 (1)
    Symbol: sym
    Info: 0x0
  }

Eric Christopher 9cad53cfec Implements low-level object file format specific output for COFF and
ELF with support for:

- File headers
- Section headers + data
- Relocations
- Symbols
- Unwind data (only COFF/Win64)

The output format follows a few rules:
- Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses.
- Hex numbers are output in uppercase, prefixed with "0x".
- Flags are sorted alphabetically.
- Lists and groups are always delimited.

Example output:
---------- snip ----------
Sections [
  Section {
    Index: 1
    Name: .text (5)
    Type: SHT_PROGBITS (0x1)
    Flags [ (0x6)
      SHF_ALLOC (0x2)
      SHF_EXECINSTR (0x4)
    ]
    Address: 0x0
    Offset: 0x40
    Size: 33
    Link: 0
    Info: 0
    AddressAlignment: 16
    EntrySize: 0
    Relocations [
      0x6 R_386_32 .rodata.str1.1 0x0
      0xB R_386_PC32 puts 0x0
      0x12 R_386_32 .rodata.str1.1 0x0
      0x17 R_386_PC32 puts 0x0
    ]
    SectionData (
      0000: 83EC04C7 04240000 0000E8FC FFFFFFC7  |.....$..........|
      0010: 04240600 0000E8FC FFFFFF31 C083C404  |.$.........1....|
      0020: C3                                   |.|
    )
  }
]
---------- snip ----------

Relocations and symbols can be output standalone or together with the section header as displayed in the example.
This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.

Patch by Nico Rieck!
