cea529dd7f lavc/opus_celt: replace pow(2,x) by exp2f(x)
Faster methods possible; since exponent is always a multiple of 1/8.

97d2c2d678 lavc/opus_celt: replace pow by exp2
exp2 is faster.

It may be possible to optimize further; e.g the exponents seem to be
multiples of 0.25. This requires study though.

Conflicts:

	libavcodec/version.h

Fate tests pass with both avresample as well as swresample based opus decoder, but
are disabled (reference files are very large so i want to think a day or 2 about
if theres an alternative or if they could be avoided, they also dont match the
official samples)
