dcd713ce06 Define the unified target inside the CMake project, and export it. 
This is less error-prone.

Merge pull request #3917 from facebook/targetCBlock_moreRegular 
More regular block sizes with `targetCBlockSize`

8d31e8ec42 sizeBlockSequences() also tracks uncompressed size 
and only defines a sub-block boundary when
it believes that it is compressible.

It's effectively an optimization,
avoiding a compression cycle to reach the same conclusion.

cc4530924b speed optimized version of targetCBlockSize 
note that the size of individual compressed blocks will vary more wildly with this modification.
But it seems good enough for a first test, and fix the speed regression issue.
Further refinements can be attempted later.

40874d4aea enriched vocabulary again 
using real latin sentences from Cicero.

Compression ratio lower again, closer to "real" text,

now level 6 is way better than level 4.

level 5 is still lower than level 4,
but at least it's now higher than level 3.

1e046ce7fa increase vocabulary size 
makes compression a bit less good,
hence a bit more comparable with real text (though still too easy to compress).
level 6 is now stronger than level 4, by a hair.
However, there is still a ratio dip at level 5.

b921f1aad6 Reduce scope of variables 
This improves readability, keeps variables local, and
prevents the unintended use (e.g. typo) later on.
