8252583: Clean up unused phi-to-copy degradation mechanism
...
Remove unused notion of 'PhiNode-to-copy degradation', where PhiNodes can be
degraded to copies by setting their RegionNode to NULL. Remove corresponding
PhiNode::is_copy() test, which always returned NULL (false). Assert that
PhiNodes have an associated RegionNode in PhiNode::Ideal().
