I was told it fixed compilation+fate on macos, but I'd prefer if the
one attached here was tested also.

It applies the same changes to ff_hevc_put_hevc_bi_w*.

Note: the pmulw/pmulhw sequence is sketchy too, but I don't intend to
fix it. I guess that using SIMPLE_LOAD does not give you the best
packing to apply pmaddwd and reduce the number of regs.

Best regards,
