Add optimized version of memcpy for Cortex A9

Adds new code to memcpy function, optimized for Cortex A9.
Adds new ARM-only loop, for operations where source and
destination are aligned.

Copyright (C) ST-Ericsson SA 2010

Modified neon implementation to fit Cortex A9 cache line size,
for those running 32 bytes L2 cache line size.
Also split the implementation in aligned and unaligned access,
for those that allows unaligned memory access with Neon.
For totally aligned operations, arm-only code is used.
