Even Rouault fd0dc535ad IDWT 5x3: generalize SSE2 version for AVX2 
Thanks to our macros that abstract SSE use, the functions can use
AVX2 when available (at compile time)

This brings an extra 23% speed improvement on bench_dwt in 64bit builds
with AVX2 compared to SSE2.

Even Rouault fa55b52d19 Improve performance of inverse DWT 5x3 (#953) 
* Use single-pass lifting inverse wavelet transform.
* For vertical pass, use SSE2 when available so as to process 8 columns
  in parallel. This is the most beneficial improvement, since the
  vertical pass involves a lot of cache trashing.

With the bench_dwt utility with default arguments (16383x16383 image),
time goes from 4.064 s to 1.212 s.
