valvar_pool, flooded and perm.. Initialize and use cselib. Log
operations. Move some code to count_with_sets and add_with_sets.

Clear dst_can_be_shared. If set->traversed_vars is non-NULL and
different from set->vars, look up slot again instead of using the
passed in slot.
(dataflow_set_init): Initialize traversed_vars.
(variable_union): Use shared_hash_*. Use initially NO_INSERT
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.
Even ->refcount == 1 vars must be unshared if set->vars is shared
and var needs to be modified.

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,
free it afterwards. If ENABLE_CHECKING verify that after noting
differences to an empty set value_chains hash table is empty.
(vt_initialize): Initialize value_chains and value_chain_pool.
(vt_finalize): Delete value_chains htab, free value_chain_pool.
