Added flag for x86 SSE compilation.
Implemented NEON intrinsics for MatX (*.h, *.cpp not done yet) and VecX.
Added missing reference to UINT_PTR in sys_defines.
Added missing reference to arm_neon.h in sys_includes.
Implemented ZeroCacheLine and FlushCacheLine in sys_intrinsics.h
Readded NEON ASM to BufferObject.cpp (after some thought, going to remove ASM, but want to commit first)
All ASM in qnx_cpu uses NEON now and removed VFP code.
