[PDB] Support executables and source/line info.

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.

[llvm-pdbdump] Very minor code cleanup.

This just removes some dead enums as well as some debug flushes
of stdout.

Fix the build, I forgot to check that UnitTests still built.

Fix warning due to unused private member variable.

Convert std::make_unique<> to llvm::make_unique<>.

Add missing function and header include.

Rewrite llvm-pdbdump in terms of LLVMDebugInfoPDB.

This makes llvm-pdbdump available on all platforms, although it
will currently fail to create a dumper if there is no PDB reader
implementation for the current platform.

It implements dumping of compilands and children, which is less
information than was previously available, but it has to be
rewritten from scratch using the new set of interfaces, so the
rest of the functionality will be added back in subsequent commits.

DebugInfoPDB: Make the symbol base case hold an IPDBSession ref.

Dumping a symbol often requires access to data that isn't inside
the symbol hierarchy, but which is only accessible through the
top-level session. This patch is a pure interface change to give
symbols a reference to the session.

Some cleanup for libpdb.

This patch implements a few of the optional suggestions from the
initial patch comitting libpdb. In particular, it implements a
virtual function out of line for each of the concrete classes.

A few other minor cleanups exist as well, such as using override
instead of virtual, etc.

Consistently use override rather than virtual.

This fixes -Winconsistent-missing-override warnings.

Change RHS-style decltype to LHS-style decltype<declval()>.

Seems some compilers don't like the RHS-style decltype specifier.

This should fix the buildbots.

Resubmit unittests for DebugInfoPDB.

These were originally submitted as part of r228428, but this part
caused a build breakage in LLVMConfig. The library portion was
resubmitted independently since it was not causing breakage.

There were two reasons this was causing the build to fail. The
first is that there were no Makefiles added for the PDB tests. And
the second is that the DebugInfoPDB library was only being built by
CMake behind an "if (MSVC)" check. This is wrong since this the
library hides platform specific details, and it was causing
LLVM-Config to not find the library when trying to build unittests.

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.
