In multi-threaded WMO builds, the frontend didn't properly handle per-file supplementary outputs specified via output file maps or command-line arguments. This enables swift-driver to use -supplementary-output-file-map for per-file outputs in multi-threaded WMO, instead of generating multiple individual flags that the frontend rejects.
