Ng Zhi An ebdc98824f [wasm-simd] Improve i8x16 shift ins-sel and temps usage 
We no longer require dst == src (output = input[0]) in all cases, only
when AVX is not supported. This can help remove an extra move when AVX
is supported. Also in many cases (when input[0] is an immediate), we
require less temporary registers.
