Rafael Espindola 2e60ca964c Pass a unique_ptr<MemoryBuffer> to the constructors in the Binary hierarchy.
Once the objects are constructed, they own the buffer. Passing a unique_ptr
makes that clear.

Rafael Espindola 6304e94108 Pass a std::unique_ptr& to the create??? methods is lib/Object.
This makes the buffer ownership on error conditions very natural. The buffer
is only moved out of the argument if an object is constructed that now
owns the buffer.

Rafael Espindola 4f7932b2fe Convert a few methods to use ErrorOr.
It used to be inconvenient to mix ErrorOr and UniquePtr, but with c++11
they work OK together.

Kevin Enderby 1983fcf86c Change the output of llvm-nm and llvm-size for Mach-O universal files (aka
fat files) to print “ (for architecture XYZ)” for fat files with more than
one architecture to be like what the darwin tools do for fat files.

Also clean up the Mach-O printing of archive membernames in llvm-nm to use
the darwin form of "libx.a(foo.o)".

Kevin Enderby 4b8fc281d4 Teach llvm-size to know about Mach-O universal files (aka fat files) and
fat files containing archives.

Also fix a bug in MachOUniversalBinary::ObjectForArch::ObjectForArch()
where it needed a >= when comparing the Index with the number of
objects in a fat file.  As the index starts at 0.

Rafael Espindola 3acea39853 Don't use 'using std::error_code' in include/llvm.
This should make sure that most new uses use the std prefix.

Ahmed Charles 56440fd820 Replace OwningPtr<T> with std::unique_ptr<T>.
This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.

Rafael Espindola 692410efcb Be a bit more consistent about using ErrorOr when constructing Binary objects.
The constructors of classes deriving from Binary normally take an error_code
as an argument to the constructor. My original intent was to change them
to have a trivial constructor and move the initial parsing logic to a static
method returning an ErrorOr. I changed my mind because:

* A constructor with an error_code out parameter is extremely convenient from
  the implementation side. We can incrementally construct the object and give
  up when we find an error.
* It is very efficient when constructing on the stack or when there is no
  error. The only inefficient case is where heap allocating and an error is
  found (we have to free the memory).

The result is that this is a much smaller patch. It just standardizes the
create* helpers to return an ErrorOr.

Almost no functionality change: The only difference is that this found that
we were trying to read past the end of COFF import library but ignoring the
error.

Chandler Carruth 8a8cd2bab9 Re-sort all of the includes with ./utils/sort_includes.py so that
subsequent changes are easier to review. About to fix some layering
issues, and wanted to separate out the necessary churn.

Also comment and sink the include of "Windows.h" in three .inc files to
match the usage in Memory.inc.

Charles Davis 1827bd8a6c 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.
