These are mostly floating-point SSE operations. The odd ones out are MOVMSK and CVTxx2yy, the others are straightforward. Unary operations are a bit special in AVX because they have 2 operands for PD/PS operands (VEX.vvvv must be 1111b), and 3 operands for SD/SS. They are handled using X86_OP_GROUP3 for compactness.
