pre-allocating a sorted[] array for most common cases of small
alphabet size cuts a lot of traffic.

This will well isolate contributions for original code,
generated code and SIMD (especially for Android).

We add the following MSA optimized color transform functions:
- AddGreenToBlueAndRed
- TransformColorInverse

(cherry picked from commit 06a38c7b1c)
This is essentially a revert of a3611513d2
and cfbcc5ece0.
Here is what happened: there was a corruption bug that eventually
got fixed by 0174d18d8b.
But before finding the root, a3611513d2
and cfbcc5ece0 hid the bug
by not imposing length of 1 when it was actually 2 or 3 (which does help
compression as a litteral is more efficient than an offset and a length
of size 2 or 3).
Change-Id: I6f18fc1f583a51ac9d8aab2508458264047cd493
convert the assert() to an error check to avoid crashing when reading
malformed files.

We only perform a single pass, and swap the final histograms
into the beginning of the array as we go. Therefore, they are
already at the correct place at the end of the pass.
-> HistogramCompactBins() is removed, we just truncate the array.
output is bitwise the same.
