Andreas Rheinhardt 0b4e69cc87 avcodec/aacdec_common: Avoid superfluous VLC structures for SBR VLCs 
For all VLCs here, the number of bits of the VLC is
write-only, because it is hardcoded at the call site.
Therefore one can replace these VLC structures with
the only thing that is actually used: The pointer
to the VLCElem table.
