db347280eb vorbis: fallback to normal division instead of crashing
The use of ff_inverse speeds up slightly arches + compilers that
do not provide a division faster than the whole machinery, such
as ppc32 + gcc4.7, but has operational limits.

Drop the always-enable assert and provide a fallback.

Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.

714508bcb9 vorbisdec: ensure FASTDIV denominator is never 1
In both usages of FASTDIV the denominator might be 1.

Using a branch could make the function slower than using a normal
division.

Both denominator and numerator can be multiplied by 2 safely and
using shifts is faster than using a branch.
