Summary:
This patch adds basic support for reading minidump files. It contains
the definitions of various important minidump data structures (header,
stream directory), and of one minidump stream (SystemInfo). The ability
to read other streams will be added in follow-up patches. However, all
streams can be read even now as raw data, which means lldb's minidump
support (where this code is taken from) can be immediately rebased on
top of this patch as soon as it lands.
As we don't have any support for generating minidump files (yet), this
tests the code via unit tests with some small handcrafted binaries in
the form of c char arrays.

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.

Continue to present HSA metadata as YAML in ASM and when output by tools
(e.g. llvm-readobj), but encode it in Messagepack in the code object.

Add data structure to represent MessagePack "documents" and convert
to/from both MessagePack and YAML encodings.
Differential Revision: https://reviews.llvm.org/D48175
llvm-svn: 346978
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 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.
