8003237: G1: Reduce unnecessary (and failing) allocation attempts when handling an evacuation failure
Summary: Remember for every generation whether the memory for that generation has already been exhausted. If so, do not try to get a new region for these generations. Further, if the last generation is full, early exit from copy_to_survivor_space.
