[PATCH] D65677: [VirtualFileSystem] Make the RedirectingFileSystem hold on to its own working directory.

[Pavel Labath via Phabricator via llvm-commits]

Though I am not very familiar VFS, this seems like the most intuitive solution out of everything that we had so far. But... shouldn't you also check that the directory you're `chdir`-ing into "exists" before you actually change the cwd? Also, the chdir operation should probably follow the usual semantics of a non-absolute chdir path being treated as relative to the previous cwd. And lastly :), what is the initial cwd value? Since previously the class shared the cwd with the underlying filesystem, one option might be to fetch the initial cwd from there (though I don't know if that is actually desired). Another option might be to just pick the first directory in the yaml file or something...
