RFR: 8365937: post_method_exit might incorrectly set was_popped_by_exception and value in the middle of stack unwinding [v4]

[Leonid Mesnik]

> The void `JvmtiExport::post_method_exit(JavaThread* thread, Method* method, frame current_frame) `calculates
>   `bool exception_exit = state->is_exception_detected() && !state->is_exception_caught();`
> to find if method exit normally or by exception.
> However, JvmtiExport::post_method_exit( method is not called at all in the case of exception. See
> `void JvmtiExport::notice_unwind_due_to_exception(JavaThread *thread, Method* method, address location, oop exception, bool in_handler_frame)`
> where post_method_exit_inner is called directly.
> 
> The `exception_exit` is true when exception is processed and the current method is called in the middle of stack unwinding.
