Please review the webrev at:


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

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