ea1d07aed9 lavc/golomb: add value range comment for set_ue_golomb(). 
set_ue_golomb just support 2^16 - 2 at most, becase this function call
put_bits, and put_bits just support write up to 31 bits, when write 32
bit in put_bits, it's will overwrite the bit buffer, and the default
assert level is 0, the av_assert2(n <= 31 && value < (1U << n)) in
put_bits can not be trigger runtime.

e639d09199 mdec: stop preferring the simple IDCT. 
This was added in e3e3c82555, probably
as a workaround for the fact that the quant table was not permutated
and the IDCT coefficients are, meaning that you'd only get correct
reconstruction if the IDCT permutation was an identity matrix, which
happens to be the case when you use the simple IDCT. The quant table
permutation bug was fixed in 42dd1434bf,
meaning this workaround is no longer necessary.

In practical terms, before 42dd1434bf,
the PSNR between decodes of the fate-mdec using simple (C) or simplemmx
IDCTs was 35. After 42dd1434bf, it's 90.
