[PDB] Emit S_UDT records in LLD. Previously these were dropped. We now understand them sufficiently well to start emitting them. From the debugger's perspective, this now enables us to have debug info about typedefs (both global and function-locally scoped) Differential Revision: https://reviews.llvm.org/D55228 llvm-svn: 348306
