Rewrite mid_pred function in generic mathops.h, reduce branch jump to improve
performance. And because nowadays new version compiler can compile enough short
asmbbely code as handwritting in these function, so remove specified optimized

Hello, Michael, can you help to review this pacth? It made ffmpeg compilable on
mips r6 platform.

Compile with generic mid_pred function written in the old way on the mips
platform, and objdump its .o file, it will show like this, with more
instructions and branch jump. ```code mid_pred(int, int,
