d6f66aec50 mips/fft: remove some useless assembly 
Remove some assembly that the compiler can easily handle optimally on its own.

213e823dc6 mips/mathops: remove 64-bit code 
GCC is perfectly happy generating optimized multiplication code on its own for
64-bit arches. GCC refuses to optimize the loongson code when in 32-bit mode,
so I've left that.

e0c7ba40cf takdec: pad filter coeff buffer for DSP functions

function requirements of having batches of 16 elements to process.

Instead, pad the buffer with 0 where the DSP functions are overreading.

2a72b1664d avcodec/h264: use avpriv_find_start_code() in h264_split()

And it should be faster, the function is not speed relevant though as it is
generally only called a few times at the streams start.
