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.

5fe64d88f6 x86: allow using add_hfyu_median_prediction_cmov on any cpu with cmov 
For some reason add_hfyu_median_prediction_cmov is only selected
on 3Dnow-capable CPUs, even though it uses no 3Dnow instructions.
This patch allows it to be selected on any cpu with cmov with the
possibility of being overridden by the mmxext version.

9699b3a2d7 mss12: avoid unnecessary division in arith*_get_bit() 
That division can be replaced with a comparison:

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

5e997688f8 h264: Remove an assert on current_picture_ptr being null 
It is possible in various error paths as well as gap handling
that this has already been allocated. It is not clear why that
would be a problem with the current code, thus disable the
assert to avoid a common assert failure when asserts are enabled.

6d9e74cd41 proresenc: Write the full value in one put_bits call 
Previously, the put_bits call writing the value wrote a value
larger than the number of bits specified, failing asserts

since the overwritten bit already always was set to 1.

aa264da5bf adpcmenc: Calculate the IMA_QT predictor without overflow 
Previously, the value given to put_bits was 10 bits long for positive
predictors, even though 9 bits were to be written. The extra bit could
in some cases overwrite existing bits in the bitstream writer cache.

This fixes a failed assert in put_bits.h, when running a version
built with -DDEBUG.

The fate test result gets slightly improved, thanks to getting rid
of the overwritten bits in the bitstream writer cache.
