Add cache preload facility
This can do the lstat() storm in parallel, giving potentially much
improved performance for cold-cache cases or things like NFS that have
weak metadata caching.
Just use "read_cache_preload()" instead of "read_cache()" to force an
optimistic preload of the index stat data. The function takes a
pathspec as its argument, allowing us to preload only the relevant
portion of the index.
