RFR: 8199471: Enable generation of callSiteForms at link time

[Paul Sandoz]

Invokers.java

Looks good.

Minor comment:

 664     /* Placeholder class for Invokers generated ahead of time */
 665     final class Holder {}
 666 
 667     /* Placeholder class for callSiteForms generated ahead of time */
 668     final class CSHolder {}

is it easy for you to change, for clarity, Holder to InvokersHolder and CSHolder to CallSiteHolder?

Thanks,
Paul.
