[10] RFR: 8178384: Reduce work in java.lang.invoke initializers

[Claes Redestad]

Hi,

profiling initializers in java.lang.invoke shows we're still doing 
various things during
class initialization which could be done lazily or not at all. The 
proposed patch
reduce bytecode executed, memory churn and retained heap footprint when
initializing java.lang.invoke:

Bug: https://bugs.openjdk.java.net/browse/JDK-8178384

Testing: java.lang.invoke jtreg tests, sanity performance testing

Thanks!
