so that no two weak alist vectors share a spine.
(scm_hash_fn_create_handle_x): Deal with a possible rehashing
during GC before inserting the new alist cell.
the prototypical examples mentioned in the old reference manual.
Instead keep the old semantics of dispatching on type. (Yes, this
is extremely ugly, but the whole point of keeping the deprecated
interface is not to break old code.)
integer-expt and multiply/divide. Inexacts and fractions no longer
supported (they happened to work before for left shifts, but not
right). Don't really need inexacts and fractions, since ash is
documented as a "bitwise operation", and all the rest of those only
take exact integers.
(tag_table_to_type_alist): ignore unknown types.
* gc.c (s_scm_gc_live_object_stats): new GUILE callable: return
statistics on the number of live objects of each type.
* gc-card.c (scm_i_tag_name): new function.
(scm_i_card_statistics): new function.
* gc-segment.c (scm_i_all_segments_statistics): new function.
(scm_i_heap_segment_statistics): new function
* gc.c (s_scm_gc_live_object_stats): new GUILE callable: return
statistics on the number of live objects of each type.
* gc-card.c (scm_i_tag_name): new function.
(scm_i_card_statistics): new function.
