[PATCH] Use memcpy instead of memove for RADEONSwapCopy.

[Pauli Nieminen]

memcpy has about 25% better performance than memmove when
destination is GTT (wc caching). Changing memmove to memcpy
in SwapCopy will reduce CPU time spent moving data between
host and GPU.

memcpy will specially help Xv when playing high resolution
videos.

The swap path doesn't support overlapping memory copies either
so extra safety is not worth the performance hit in commonly
used code path.
