paboyle 04072a5e1f Rotate is a temporary hack. Would like to merge ALL ...

permutes as rotates of length 2, and make any rotate active
over any subset of lane bits. This is hard, and requires general
permute; current intrinsics mean this is only really possible for specific
case by case encodings as presently performed. Intel could produce a general
permute.. would help. IBM did it in VMX.
