Fritz Koenig 93c32a55c2 Rework idct calling structure.
Moving the eob structure allows for a non-struct based
function to handle decoding an entire mb of
idct/dequant/recon data.  This allows for SIMD functions
to idct/dequant/recon multiple blocks at once.

SSE2 implementation gives 3% gain on Atom.
