This fixes a number of endianness issues as well as an ODR
violation that hopefully causes everything to be happy.

r267049 broke multiple buildbots (e.g. clang-cmake-mips, and clang-x86_64-linux-selfhost-modules) which the follow-ups have not yet resolved and this is preventing subsequent committers from being notified about additional failures on the affected buildbots.

PDB parsing code was hand-rolled into llvm-pdbdump. This patch moves the
parsing of this code into DebugInfoPDB and makes the dumper use this.
This is achieved by implementing the skeleton of RawPdbSession, the
non-DIA counterpart to the existing PDB read interface. None of the type /
source file / etc information is accessible yet, so this implementation is
not yet close to achieving parity with the DIA counterpart, but the
RawSession class simply holds a reference to a PDBFile class which handles
parsing the file format. Additionally a PDBStream class is introduced
which allows accessing the bytes of a particular stream in a PDB file.

Previously DebugInfoPDB could only load data for a PDB given a
path to the PDB. It could not open an EXE and find the matching
PDB and verify it matched, etc. This patch adds support for that
so that we can simply load debug information for a PDB directly.
Additionally, this patch extends DebugInfoPDB to support getting
source and line information for symbols.

Previously it was impossible to distinguish between "There is
no PDB implementation for this platform" and "I tried to load
the PDB, but couldn't find the file", making it hard to figure
out if you built llvm-pdbdump incorrectly or if you just mistyped
a file name.
This patch adds proper error handling so that we can know exactly
what went wrong.

This implements DebugInfoPDB when the DIA SDK is present on the system.
Specifically, this means that the following conditions are met:
1) You are building on Windows.
2) You are building with MSVC.
3) Visual Studio did not corrupt the installation of DIA due to a
known issue with side-by-side installations of VS2012 and VS2013.
If all of these conditions are true, you will be able to pass a value
of PDB_Reader::DIA to PDB::createPdbReader().
There are no tests for this yet, as any test will be in the form of a
lit test which tests the llvm-pdbdump.exe, which still needs to be
rewritten in terms of this library.

This change resubmits the patch that broke the build, this time
without unittests. The unittests will be submitted separately
after the problem has been addressed:
--Original Commit Message--
Create lib/DebugInfo/PDB.
This patch creates a platform-independent interface to a PDB reader.
There is currently no implementation of this interface, which will
be provided in future patches. This defines the basic object model
which any implementation must conform to.
