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.

Commit 29313eb5 introduced those flags to avoid issues with
-fsanitize=unsigned-integer-overflow
However it is better just to rewrite the loop to avoid such condition
to occur.

Even Rouault 73d1510d47 Encoder: fix packet writing of empty sub-bands (#891, #892)
There are situations where, given a tile size, at a resolution level,
there are sub-bands with x0==x1 or y0==y1, that consequently don't have any
valid codeblocks, but the other sub-bands may be non-empty.
Given that we recycle the memory from one tile to another one, those
ghost codeblocks might be non-0 and thus candidate for packet inclusion.
