RFR: JDK-8282798 java.lang.runtime.Carrier [v10]

[Jim Laskey]

> We propose to provide a runtime anonymous carrier class object generator; java.lang.runtime.Carrier. This generator class is designed to share anonymous classes when shapes are similar. For example, if several clients require objects containing two integer fields, then Carrier will ensure that each client generates carrier objects using the same underlying anonymous class. 
> 
> See JBS for details.

Jim Laskey has updated the pull request incrementally with three additional commits since the last revision:
