      Description

      LambdaForms which are generated for invokedynamic contains significant part of code responsible for class initialization check/invocations.
      If we force class initialization from InnerClassLambdaMetafactory we get +6% - +10% performance improvement to lambda linkage (due to LF tree simplification).

      Minor performance improvement: merging two subsequent "doPrivileged" actions into one gives ~+1%.

      Attached webrev contains fix: please review.
