Implement these 4 instructions for x64 Liftoff: - i64x2.widen_low_i32x4_s - i64x2.widen_high_i32x4_s - i64x2.widen_low_i32x4_u - i64x2.widen_high_i32x4_u We move the codegen for the *high* instructions into macro-assembler to allow sharing of the optimized code sequence between TurboFan and Liftoff.
