Thanks to Tom for finding the cause of the problem.

Fixed 6710487: More than half of JDI Regression tests hang with COOPs in -Xcomp mode
DecodeNNode::decode() and EncodePNode::encode() contains
Identity transformation (may return a preexisting ideal node)
which could create a circle during gvn transformation.
Don't return a preexisting ideal node when a new node expected.
I think it is OK to return a preexisting node if it used as
an input edge for an other new node (for example, in StoreNode::make()).
Fix verified (y/n): y
