[PATCH 22/45] check-ignore: convert to use parse_pathspec

check-ignore (at least the test suite) seems to rely on the pattern order. PATHSPEC_KEEP_ORDER is introduced to explictly express this. The lack of PATHSPEC_MAXDEPTH_VALID is sufficient because it's the only flag that reorders pathspecs, but it's less obvious that way.
