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.

For some reason add_hfyu_median_prediction_cmov is only selected

This patch allows it to be selected on any cpu with cmov with the
possibility of being overridden by the mmxext version.

That division can be replaced with a comparison:

By expanding 'range' definition and simplifying this inequation we obtain
the final expression.
