        Description

        To reduce the C2 compiler's memory usage, JDK-8011858 changed memory allocation for compiler-related data structures to use Compile::live_nodes() instead of Compile::unique_nodes(). While backporting JDK-8011858 to 8u72, we've discovered two code locations where live_nodes() and be used instead of unique_nodes().

        This issue looks into whether allocation at these two code locations can be adjusted for 9 as well. Also, the current issue looks into other code locations where an adjustment is possible.
