C2: Add "TraceSplitIf" flag to get more information about the optimization in Split-If

XMLWordPrintable

      Split-If is quite complex and it would benefit to add "TraceSplitIf" flag to get more information about the optimisation. Note that JDK-8330469 removed the "PrintOpto && VerifyLoopOptimizations" flag combination guarding some logging information in Split-If as this flag combination is not used in practice.

      Interesting things to log (not an exclusive list):
      - If node which is split through
      - Nodes being cloned up (split_up())
      - Nodes being cloned down (clone_*_down())
