History
Gvozden Neskovic ae25d22235 Add RAID-Z routines for SSE2 instruction set, in x86_64 mode. 
The patch covers low-end and older x86 CPUs.  Parity generation is
equivalent to SSSE3 implementation, but reconstruction is somewhat
slower.  Previous 'sse' implementation is renamed to 'ssse3' to
indicate highest instruction set used.
