Michael J. Spencer 7e48b406ef [Driver] Fix -working-directory issues 
Currently the `-working-directory` option does not actually impact the working
directory for all of the clang driver, it only impacts how files are looked up
to make sure they exist.  This means that that clang passes the wrong paths
to -fdebug-compilation-dir and -coverage-notes-file.

This patch fixes that by changing all the places in the driver where we convert
to absolute paths to use the VFS, and then calling setCurrentWorkingDirectory on
the VFS.  This also changes the default VFS for `Driver` to use a virtualized
working directory, instead of changing the process's working directory.
