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.
