[PATCH 20/25] list-files: preload index

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Try to reduce refresh time. Note that we still need another
read_cache() at top top, before parse_pathspec() because this
*_SLASH_CHEAP needs the index loaded.

One day read_index() should be improved to notice that the on-disk
version is the same as the one in memory and skip I/O entirely..
