[SPARK-12030] Fix Platform.copyMemory to handle overlapping regions.
This bug was exposed as memory corruption in Timsort which uses copyMemory to copy
large regions that can overlap. The prior implementation did not handle this case
half the time and always copied forward, resulting in the data being corrupt.

Closes #10068 from nongli/spark-12030.
