AMD embraces AVX making a new superset with SSE5(256bit support)

This document from spring 2008 already shows that FMA is post Sandy Bridge
(see page 23 and on)

That has changed now AVX and FMA is considered different. AVX will come in SB but FMA will come in its shrink. It will be 256bit wide but using 128bit x2 route its easy to implement.
