472a3333a8 8067336: Allow that PLAB allocations at the end of regions are flexible 
PLAB allocations may return a buffer that is between minimum size (current allocation) and the desired size. This allows removes a large amount of fragmentation at the end of regions.

6cca258181 8040162: Avoid reallocating PLABs between GC phases in G1 
Allocate G1ParScanThreadState at the start of GC and only deallocate at the end of GC. This automatically keeps the current PLAB intact without flushing it (and loosing lots of memory) for every reallocation.

8c2da662ff 8003237: G1: Reduce unnecessary (and failing) allocation attempts when handling an evacuation failure 
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.
