Revert "Fix the build broken by r189315." and "Move everything depending on Object/MachOFormat.h over to Support/MachO.h."

This reverts commits r189319 and r189315. r189315 broke some tests on what I
believe are big-endian platforms.

* ELFTypes.h contains template magic for defining types based on endianess, size, and alignment.
* ELFFile.h defines the ELFFile class which provides low level ELF specific access.
* ELFObjectFile.h contains ELFObjectFile which uses ELFFile to implement the ObjectFile interface.

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.

llvm-svn: 186734

Because it broke s390x and ppc64-linux buildbots. This reverts commit r186623.

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.

I wish we could typecheck llvm::format.

These records are mandatory for executables and are used by the loader.

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.

It was only implemented for ELF where it collected the Addend, so this
patch also renames it to getRelocationAddend.

Build attribute sections can now be read if they exist via ELFObjectFile, and
the llvm-readobj tool has been extended with an option to dump this information
if requested. Regression tests are also included which exercise these features.

Also update the docs with a fixed ARM ABI link and a new link to the Addenda
which provides the build attributes specification.

llvm-svn: 181009

getRelocationAddress is for dynamic libraries and executables,
getRelocationOffset for relocatable objects.

Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a
test of ELF's. llvm-readobj -r now prints the same values as readelf -r.

llvm-svn: 180259

While here, don't report a dummy symbol for relocations that don't have symbols.
We used to says such relocations were for the first defined symbol, but now we
return end_symbols(). The llvm-readobj output change agrees with otool.

We are still able to handle mixed endian objects by swapping one struct at a
time.

We are now able to handle big endian macho files in llvm-readobject. Thanks to
David Fang for providing the object files.

This option expands shown relocations from single line to a dictionary
format:

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

llvm-svn: 179359

Original message:

Print more information about relocations.

With this patch llvm-readobj now prints if a relocation is pcrel, its length,
if it is extern and if it is scattered.

It also refactors the code a bit to use bit fields instead of shifts and
masks all over the place.

For now it is templated only on being 64 or 32 bits. I will add little/big
endian next.
