ac05f9030e Convert floating-point MDCT coefficients to 24-bit fixed-point all at once 
instead of doing it separately in 2 different functions.
This makes float AC-3 encoding approx. 3-7% faster overall.
Also, the coefficient conversion can now be easily SIMD-optimized.

9c84a72a25 Skip the bit allocation search if previous and current SNR offsets are the 
maximum value of 1023.
This speeds up overall encoding depending on the content and bitrate.
The most improvement is with high bitrates and/or low complexity content.
