     src/dispextern.h (enum bidi_dir_t): Force NEUTRAL_DIR to be zero.
     (struct bidi_stack): Reduce size by using bit fields and by
     packing sos, override, and isolate_status into a single 8-bit
     byte called 'flags'.
     src/bidi.c (ISOLATE_STATUS, OVERRIDE): New macros.
     (bidi_push_embedding_level): Construct flags from individual
     bits.  Adapt to changes in prev_for_neutral and next_for_neutral
     (bidi_pop_embedding_level): Use ISOLATE_STATUS.  Extract 'sos'
     from flags.  Adapt to changes in prev_for_neutral,
     next_for_neutral, and last_strong members.
     (bidi_line_init): Initialize flags to zero.
     (bidi_resolve_explicit, bidi_resolve_weak, bidi_resolve_brackets)
     (bidi_resolve_neutral): Use ISOLATE_STATUS and OVERRIDE.
