 * This macro defines the structure of the JVMCI classes accessed from VM code.  It is used to
 * generate accessors similar to javaClasses.hpp, but with specializations for HotSpot and JNI based
 * access.
 *
 * HotSpotJVMCI: This class contains accessors based on the VM internal
 * interface to Java. It is used for JVMCI Java code executing on the HotSpot heap.
 *
 * JNIJVMCI: This class contains JNI based accessors and is used for JVMCI
 * Java code executing in the JVMCI shared library.
