Resubmit "Create lib/DebugInfo/PDB" (r228428)

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.
