6c62841076 Split the main CMake file.
This will well isolate contributions for original code,
generated code and SIMD (especially for Android).

319e37be13 Improve lossless compression.
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).

8ec7032bc2 simplify HistogramCombineEntropyBin()
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.
