Summary:
A class that exposes a simple in-memory representation of a document of
MsgPack objects, that can be read from and written to MsgPack, read from
and written to YAML, and inspected and modified in memory. This is
intended to be a lighter-weight (in terms of memory allocations)
replacement for MsgPackTypes.
Two subsequent changes will:
1. switch AMDGPU HSA metadata to using MsgPackDocument instead of
MsgPackTypes;
2. add MsgPack AMDGPU PAL metadata via MsgPackDocument.

Add data structure to represent MessagePack "documents" and convert
to/from both MessagePack and YAML encodings.

Add support for reading and writing MessagePack, a binary object serialization
format which aims to be more compact than text formats like JSON or YAML.
The specification can be found at
https://github.com/msgpack/msgpack/blob/master/spec.md
Will be used for encoding metadata in AMDGPU code objects.

This re-lands r333797 with a fix for big endian systems.
Original commit message:
This isn't encountered anywhere inside LLVM, so I wrote a test case to expose the issue and verify that it is fixed.
The basic problem is that the macho_load_command union contains all load comamnd structs. Load command structs in 32-bit macho files can be 32-bit aligned instead of 64-bit aligned.
There are some strange circumstances in which this can be exposed in a 64-bit macho if the load commands are invalid or if a 32-bit aligned load command is used. In the past we've worked around this type of problem with changes like r264232.

This reverts commit r333803.
Still breaking on big endian. Will sort this out later.

This reverts commit r333797.
This patch is failing on BigEndian bots. I will fix and re-land:

This creates a new library called BinaryFormat that has all of
the headers from llvm/Support containing structure and layout
definitions for various types of binary formats like dwarf, coff,
elf, etc as well as the code for identifying a file from its
magic.
