[VFS] Add support to RedirectingFileSystem for mapping a virtual directory to one in the external FS. Previously file entries in the -ivfsoverlay yaml could map to a file in the external file system, but directories had to list their contents in the form of other file entries or directories. Allowing directory entries to map to a directory in the external file system makes it possible to present an external directory's contents in a different location and (in combination with the 'fallthrough' option) overlay one directory's contents on top of another. rdar://problem/72485443 Differential Revision: https://reviews.llvm.org/D94844 2021-01-15 15:33:52 +08:00			`{`
