Ng Zhi An 51a7668976 [wasm-simd] Scalar lowering for load splat (s8x16, s16x8, s32x4) 
We lower each op into num_lanes loads, and connecting up the effects in
a chain.

s64x2 is not implemented since we lowering for 64x2 generally doesn't
work anyway.

Load extends are a bit more complicated, so we'll do that in a separate
change.
