Fix EmitHighNarrow(), EmitSaturatingNarrowOp() when Rd == Rn || Rd == Rm (& Part != 0). Optimization of EmitVectorTranspose(), EmitVectorUnzip(), EmitVectorZip() algorithms (reduction of the number of operations and their complexity). Add 12 Tests about Trn1/2, Uzp1/2, Zip1/2 (V) instructions. (#268)
