fix corner case when requiring cost of an FSE symbol
...
ensure that, when frequency[symbol]==0,
result is (tableLog + 1) bits
with both upper-bit and fractional-bit estimates.
Also : enable BIT_DEBUG in /tests

[zstd] Backport kernel patch from @ColinIanKing
...
* Make the U32 table in `FSE_normalizeCount()` static.
* Patch from https://lkml.kernel.org/r/20170922145946.14316-1-colin.king@canonical.com .
* Clang makes non-static tables static anyways. gcc however, does [weird things](https://godbolt.org/g/fvTcED ).
* Benchmarks showed no difference in speed.
