https://reviews.llvm.org/D50539 didn't change `RedirectingFileSystem` behavior regarding real paths. But for `-ivfsoverlay` it started using nested `RedirectingFileSystem` instead of `OverlayFileSystem`. And `OverlayFileSystem` implements `getRealPath` <https://clang.llvm.org/doxygen/VirtualFileSystem_8cpp_source.html#l00390>.
