    Refactor PVQ codes for intra4x4 · 900243b9
    Yushin Cho authored
    In 4x4 intra search for RDO, AV1 codes has been changed to
    call av1_xform_quant() while ago, while PVQ did not but call
    txfm and pvq_encode_helper() instead, which caused duplicated codes
    and thus worse maintenance and testing.
    
    This refactor also has fixed the long-sitting bug,
    which we couldn't find before refactoring.
