Most of the time is spent in bitmap_bit_p which is called from
collect_points_to_info_for, maybe we
should be using sbitmap instead.
Note collect_points_to_info is called from merge_pointed_to_info

Note that the number of computed gotos shouldn't matter much, we
factor computed gotos to have a single common computed jump.

You could try an sbitmap for ai-ssa_names_visited in tree-ssa-alias,
and a pointer_set for visited in walk_use_def_chains_1.
