[PATCH] Improve copy prop for aggregates and combine with zeroing case

This improves copy prop for aggregates by working over statements that don't modify the access just like how it is done for copying zeros. To speed up things, we should only have one loop back on the vuse instead of doing it twice for each load/store assignments. PR tree-optimization/142
