This is an av_cold function, and we don't need to duplicate variables just to
save a few characters.

918cd2255c Simplify fix15(). 
Turn it into 2 macros, and use av_clip_int16() and lrintf().
This matches the int16 to float sample conversion in audioconvert.c.
The regression test output is different due to lrintf() rounding.
