1) Two comments ";ASSERT(lp_quantization <= 31)" in the new functions ..._wide_asm_ia32() -- just to mention this constraint. (max. possible value of lp_quantization is 15, so it's not a problem)
2) "mov cl, ..." was replaced with "mov ecx, ..." (again Agner Fog, optimizing_assembly.pdf) summary: write to a partial register may result in false dependencies between instructions, so it is better to avoid it. (also bitreader_asm.nasm and stream_encoder_asm.nasm both have "mov ecx, ..." instructions, and no "mov cl, ...").
