271f95940b libavcodec/mips: fix for mips optimized fp fft with hard coded tables disabled
Floating point FFT (nips optimized) breaks when hard coded tables are
not enabled because MIPS optimization of floating point FFT uses only
ff_init_ff_cos_tabs(16) which is not enabled by default in that case.

This patch is fixing it.

b3fdfc8c4e Optimization of AC3 floating point decoder for MIPS
FFT in MIPS implementation is working iteratively instead
 of "recursively" calling functions for smaller FFT sizes.
Some of DSP and format convert utils functions are also optimized.
