The DebugDirectory contains a pointer to the CodeView info structure which is a derivative of the OMF debug directory. The structure has evolved a bit over time, and PDB 2.0 used a slightly different definition from PDB 7.0. Both of these are specific to CodeView and not COFF. Reflect this by moving the structure definitions into the DebugInfo/CodeView headers. Define a generic DebugInfo union type that can be used to pass around a reference to the DebugInfo irrespective of the versioning.
