Similarly 464.h264ref miscompares because of
fprintf(stdout, "Freq. for encoded bitstream: %1.0f\n",
img->framerate/(float)(input->jumpd+1));
where both img->framerate and input->jumpd are input parameters
(15.0 and 1). Here the rounding to integer happens inside fprintf.
Feeding rcps sequences into call stmts is probably never a very good idea.
Mine. I'm going to move rcps expansion up into tree-ssa-math-opts, the
same place where we apply LCM for CSE-ing 1/x. Probably replace the
division by a builtin.
