We extract a sub-function from MAKENAME(_nofilter_DX), only dealing with reading
one index array, indexing into src array and output to dst array.
Because of the scatter-gather nature, we can not do much burst/batch
reading/writing to improve the performance.
We tried Neon vector instructions. We also tried the hand optimize the compiler
generated assembly (non-neon) code. The latter seems to have better gain.
About 6% improvements, not much though...
