Commit 900ce6f8c3526f27173057bb955f54f4f4f41246 replaced
IntraX8Context.ac_vlc by IntraX8Context.ac_vlc_table,
but forgot to update an av_assert2()*.
cf7ed01938a4d8b2ccd28f1fadacd79103e54eed then
replaced this with a check for j_ac_vlc[mode],
but this makes no sense as j_ac_vlc is of type
const VLCElem [2][2][8][].
Worse yet, mode can be up to three and then
j_ac_vlc[mode] is undefined behaviour. This happened
during the wmv8-x8intra FATE test.
*: Since 84f16bb5e68dc47eca4dc96b3391c58471cd7328
config.h was no longer auto-included in avassert.h
and this disabled av_assert1() and av_assert2()
in files where config.h has not been included before
the inclusion of avassert.h.
