There are three modes of concern here: 1) User provides -vfsoverlay but not -Xcc -ivfsoverlay Recommended behavior. 2) User provides -Xcc -ivfsoverlay but not -vfsoverlay Legacy behavior. Clang will handle setup for the VFS. 3) User provides both -vfsoverlay and -Xcc -ivfsoverlay Unsupported. We will ignore the clang VFS overlays and substitute our own. We will also pop a warning about this.
