Cheaper fluid-ref cache
* libguile/cache-internal.h (struct scm_cache_entry): Add needs_flush
member.
(scm_cache_evict_1): Clear needs_flush on newly evicted entry.
(scm_cache_insert): Propagate needs_flush to new entry.
* libguile/fluids.c (restore_dynamic_state): Mark all restored entries
as needing a flush.
(save_dynamic_state): Only cons on "needs_flush" entries to the
resulting dynamic state. The result is the same as before but
avoiding the refq on the weak table.
(fluid_set_x): Propagate needs_flush down to the cache.
(fluid_ref): When adding entry to cache, use needs_flush==0.
(scm_fluid_set_x, scm_fluid_unset_x, scm_swap_fluid, swap_fluid): Use
needs_flush==1.
