After https://bugs.openjdk.org/browse/JDK-8292289 , the base class of VectorTestNode changed from Node to CmpNode. So I add two match rule into ad file.

match(If cop (VectorTest op1 op2));
match(Set dst (CMoveI (Binary cop (VectorTest op1 op2)) (Binary src1 src2)));

First error, rule1 shouldn't generate the statement "node->_bottom_type = _leaf->bottom_type();".
Second error, both rule1 and rule2 need to use VectorTestNode, the VectorTestNode should be cloned like CmpNode.
