When running reproducer scripts we need that original symlinks from the source filesystem are reproduced in the VFS so that different virtual paths can map to the same file, allowing the FileManager to share the same UID between these virtual entries. This avoids all sorts of module redefinition errors when using frameworks. llvm-svn: 268825
