Currently UniqueNodeList is used for GVN oprimizations.
Unfortunately the nodes on UniqueNodeList could be shuffled
and processed not in the order they were put on the list.
With delayed IGVN processing during macro nodes expansion
it causes the problem since n->bottom_type() and igvn->type(n)
may not match.
