RFR: 8265795: vmTestbase/nsk/jvmti/AttachOnDemand/attach022/TestDescription.java fails when running with JEP 416 [v2]

[Leonid Mesnik]

> The VMObjectAlloc jvmti event was not generated for objects created using MethodHanldle. The fix adds posting of the event into Unsafe_AllocateInstance.
> 
> While fixing this bug I noticed that event is not posted in the intrinsics version for many functions where it is used. Including  but not limited to clone(), invoke()m allocateInstance() and allocateUninitializedArray(). There are might be other intensified functions (not analogs JVM_ENTRY versions) that allocate objects without post events. 
> 
> I think it is needed to implement some common way to handle this and cover it in another issue.
