Log:
 A Decl->getName() is not unique. However, the debug info descriptors 
 are uniqued. The debug info descriptor describing record's context is
necessary to keep two Decl's descriptor unique if their name match.

There is more work to do to create descriptors for DeclContext. 
As a temp. step use type's name in FwdDecl.
