Rémi Denis-Courmont 55200f999c lavc/mathops: R-V B optimisation for mid_pred
If Zbb is enabled at compilation (e.g. Ubuntu), the compiler should
compile the new C mid_pred() function correctly. But if Zbb is *not*
enabled (e.g. Debian), then we can at least fallback at run-time.

On SiFive-U74, before:
sub_median_pred_c:                                    1331.9 ( 1.00x)
sub_median_pred_rvb_b:                                 881.8 ( 1.51x)

After:
sub_median_pred_c:                                    1133.1 ( 1.00x)
sub_median_pred_rvb_b:                                 875.7 ( 1.29x)
