When upstreaming JDK-8355003, we introduced AOTCompileEagerly flag and defaulted it to disabled, to gate the training data replay. Without AOT code, this causes extra compilations, this is why it is false by default in mainline. But for Leyden, it should remain enabled, since this is the path that loads AOT compiled C2 code. We got this flag as "false" during the mainline->Leyden merge.
