Implement these 6 instructions: - f64x2.convert_low_i32x4_s - f64x2.convert_low_i32x4_u - i32x4.trunc_sat_f64x2_s_zero - i32x4.trunc_sat_f64x2_u_zero - f32x4.demote_f64x2_zero - f64x2.promote_low_f32x4 The code sequences are exactly the same as on x64. Needed to add some more instructions, and we don't have macro lists for these instructions yet, so individually define them for now. We can factor them into lists in a future change.
