> This fixes some lurking issues with JVMCI and nmethod related both BarrierSetNMethod and the garbage collection of nmethods.  In particular the stack walking in c2v_iterateFrames visits many frames and needs a KeepStackGCProcessedMark for safety.  Additionally, JVMCI interacts with nmethods in complex ways and needs some sort of strong root during these interactions.  A new JavaThread field has been added that mirrors the way JVMTI keeps nmethods alive.
