Description
Add GetLocalInstance function to JVMTI 1.2:

jvmtiError GetLocalInstance(jvmtiEnv* env, jthread thread, jint depth, jobject* value_ptr);

Calling GetLocalInstance() is equivalent to calling GetLocalObject() call for slot 0 except:  
(1) A call to GetLocalInstance() succeeds and retrieves an object out of a native frame where GetLocalObject() would return JVMTI_ERROR_OPAQUE_FRAME.
(2) GetLocalInstance() returns JVMTI_ERROR_INVALID_SLOT if called on a static method frame.
