919b448c2e [llvm-readobj] Fix another "time of check to time of use bug".
It seems there's more copy-paste between tools than needed.

793616c068 [llvm-readobj] MachO -- dump LinkerOptions load command.
Example output:

Linker Options {
  Size: 32
  Count: 2
  Strings [
    Value: -framework
    Value: Cocoa
  ]
}

There were only two tests using this -- so I converted them as part of
this commit rather than separately.

40e22518fc Re-apply r246276 - Object: Teach llvm-ar to create symbol table for COFF short import files
This patch includes a fix for a llvm-readobj test. With this patch, 
the tool does no longer print out COFF headers for the short import
file, but that's probably desirable because the header for the short
import file is dummy.

8a0ff180e8 Move to llvm-readobj code that is only used there.
lld might end up using a small part of this, but it will be in a much
refactored form. For now this unblocks avoiding the full section scan in the
ELFFile constructor.

This also has a (very small) error handling improvement.

548f2b6e8f Don't own the buffer in object::Binary.
Owning the buffer is somewhat inflexible. Some Binaries have sub Binaries
(like Archive) and we had to create dummy buffers just to handle that. It is
also a bad fit for IRObjectFile where the Module wants to own the buffer too.

Keeping this ownership would make supporting IR inside native objects
particularly painful.

This patch focuses in lib/Object. If something elsewhere used to own an Binary,
now it also owns a MemoryBuffer.

This patch introduces a few new types.

* MemoryBufferRef. This is just a pair of StringRefs for the data and name.
  This is to MemoryBuffer as StringRef is to std::string.
* OwningBinary. A combination of Binary and a MemoryBuffer. This is needed
  for convenience functions that take a filename and return both the
  buffer and the Binary using that buffer.

The C api now uses OwningBinary to avoid any change in semantics. I will start
a new thread to see if we want to change it and how.

1fca78a9b1 Return an ErrorOr<Binary *> from createBinary.
I did write a version returning ErrorOr<OwningPtr<Binary> >, but it is too

when we switch to c++11.
