bitmap.
(compute_tag_properties): Ditto.
(create_partition_for): Ditto.
(compute_memory_partitions): Ditto.
(dump_may_aliases_for): Ditto.

(init_alias_info): Initialize alias_bitmap_obstack.
(union_alias_set_into): New function.
(compute_flow_sensitive_aliasing): Use union_aliases_into.
(have_common_aliases_p): Rewrite to take two bitmaps and use
intersection.
(compute_flow_insensitive_aliasing): Stop using pointer-sets.
Update for bitmaps.
