passed in slot.
(dataflow_set_init): Initialize traversed_vars.

lookup if set->vars is shared. Don't keep slot cleared before
calling unshare_variable. Unshare set->vars if needed. Adjust
unshare_variable callers. Clear dst_can_be_shared if needed.

beginning, use it instead of local &set, don't destroy it at the
end.
(vt_emit_notes): Call dataflow_set_clear early on all
VTI(bb)->out sets, never use them, instead use emit_notes_in_bb
computed set, dataflow_set_clear also VTI(bb)->in when we are
done with the basic block. Initialize changed_variables_stack,

differences to an empty set value_chains hash table is empty.
