Fix declarations of variables related to bidi cache indices.

 src/bidi.c (bidi_cache_fetch_state, bidi_cache_search)
 (bidi_cache_find_level_change, bidi_cache_ensure_space)
 (bidi_cache_iterator_state, bidi_cache_find)
 (bidi_find_other_level_edge, bidi_cache_start_stack): All
 variables related to cache indices are now EMACS_INT.
