Only sub_media_pred has an MMXEXT version, so one can use
the version with the stricter check (that checks that
the MMX registers have not been clobbered) for sub_left_predict.

There is no MMX code for diff_bytes since commit
230ea38de1, so use declare_func
instead of declare_func_emms() to also test that we are not
in MMX mode after return.
