RFR (S) 8197844: JVMTI GetLoadedClasses should use the Access API

[Poonam Parhar]

Hi Coleen,

Fix for JDK-8187577 <https://bugs.openjdk.java.net/browse/JDK-8187577> 
added the following include too in jvmtiGetLoadedClasses.cpp file. I 
think that can also be removed now.

+#if INCLUDE_ALL_GCS
+#include "gc/g1/g1SATBCardTableModRefBS.hpp"
+#endif


Thanks,
Poonam
