> SA10178.vc1: 18 frames ok, last 7 frames are different

this one decodes correctly when you force bitexact decoding:

ffmpeg -bitexact -i SA10178.vc1 SA10178_s.yuv

This is caused by the issue that my rejected patch 'avcodec/x86/hpeldsp:
fix half pel interpolation' tried to resolve. The proposed solution to
make bitexact decoding the default for VC-1 seems right.
