The flag was and is intended to be a sane default and thus does not enable
time consuming checks. This also matches how the flag is used in decoders and
demuxers.

Don't use word-size multiplications if size == 2, and if we're using
SIMD instructions (size >= 8), complete leftover 4byte sets using movd,
not mov. Both of these changes lead to minor speedups.

Fixes out of array read
This issue can be reproduced with:
Lucky.asf
teuflisch.asf
from http://samples.ffmpeg.org/A-codecs/VoxWare/
as well as other samples
fcb16m has 320 elements but the code before the patch can address a
table of 384 elements in its place.
I dont know if theres some elements missing, or its maybe the wrong
table, or if the parameters affecting the table size are wrong, or
if theres something else wrong.
if someone reading this has easy access to some reference. (binary
with the tables in it, spec, whatever, please contact us)
This solution fixes the inconsistency by padding the table with zeros,
this variant was suggested by Vitor Sessak. And ensures that nothing
currently working breaks.
