rev 7539 : 8011858: Use Compile::live_nodes() instead of Compile::unique() in appropriate places
Reviewed-by: kvn, vlivanov

*** 325,335 ****
// Identify all nodes that are reachable from below, useful.
// Use breadth-first pass that records state in a Unique_Node_List,
// recursive traversal is slower.

// Initialize worklist
