See ~~JDK-8357017~~ and ~~JDK-8258229~~ for examples of problems caused by NativeJump::patch_verified_entry().

Recent JDK releases always use nmethod entry barriers, and already have support for redirecting to SharedRuntime::get_handle_wrong_method_stub(). We can replace verified entry point patching with a permanently armed entry barrier.
