The reader reads in chunks of 11 bits at most, and at most 3 times. The unsafe
reader therefore may read 6 chunks instead of 1 in worst case, ie 8 bytes,
which is within the padding tolerance.
The reader ends up being ~10% faster. Cumulative effect of unsafe reading and
code block swapping on 3 sequences is for 1 thread, decoding time goes from
23.3s to 19.0s.

The old code was reserving the 0xFFFF entry to represent an inexisting
entry/codeword. These entries are now detected through their length
being <= 0. As this entry is often used for the residuals (-1,-1), which
should be among the most frequent, it is particularly important to not
reserve it.

The effect is not really deterministic, as it seems to be a combination
on x86_64 of fewer registers used, different jump offsets and, for all
archs, of likely branches.
Speedup is around 15%.

An invalid entry already has the property of having a negative number
of bits, so remove the check on the reserved value, and rearrange the
code as a consequence.

When the joint table does not contain a valid entry, the decoding restarts
from scratch. By implementing the trick of jumping to the 2nd level of the
individual table (and inlining the whole), a speed improvement of 5-10%
is possible.
